GENES ENCODING AMINO ACID TRANSPORTER, CYANOGLOBIN FOUND IN NIF REGION
MARTIN MULLIGAN informs us of provocative results stemming from his recent
sequencing of the region upstream of nifB in Anabaena PCC 7120. The sequenced
region lies at the boundary of a large segment of DNA containing genes
involved in nitrogenase synthesis and maturation. Two or possibly three open
reading frames (ORFs) were found oriented away from nifB. The first ORF is
highly homologous to amino-acid transport proteins, in particular to ArcD
from Pseudomonas and, less so, to a membrane protein recognized by a mouse
retrovirus. ArcD is postulated to be an arginine/ornithine antiport protein,
and the viral receptor is known to transport neutral amino acids. Hydropathy
plots indicate that the ORF codes for an integral membrane protein, as would
be expected for a transporter.
The location of the ORF near the nif genes might recall to mind
predictions that there should be transport systems between cells along the
filament mediating the transfer of nitrogenous compounds, perhaps induced by
nitrogen deprivation [e.g. Haselkorn R (1978) Annu Rev Plant Physiol 29:319-
344]. Previously described transport systems for basic amino acids in
Anabaena PCC 7120 are not inducible [Herrero A, Flores E (1990) J Biol Chem
265:3931-3935]. M.L. Montesinos, Antonia Herrero, and ENRIQUE FLORES now tell
us that they have characterized two transport systems for neutral amino
acids, also non-inducible, in Anabaena PCC 7120 and in derivatives mutated
in one or both systems. It is of course unclear whether the gene discovered
by Mulligan corresponds to any of these non-inducible systems or to some
presently unknown activity.
MARTIN MULLIGAN also found in Nostoc MUN 8820a gene encoding a myoglobin-
like protein, called cyanoglobin. Such a gene (glbN) was previously described
in Nostoc commune [Potts et al (1992) Nature 256:1690-1691], but it is not
generally found in heterocystous cyanobacteria. The two genes are similar but
not identical and in each case is located between nifU and nifH. It would be
nice to know if the presence or absence of cyanoglobin in a cyanobacterium
is related to some ecological need, but unfortunately, the history of Nostoc
MUN 8820 is obscure. It was derived from a culture obtained several years
from the G�ttingen culture collection (SAG), labelled Oscillatoria tenuis
1459-4, but the designation is clearly inaccurate. The true source of Nostoc
MUN 8820 is probably lost forever.
LIGHT-DEPENDENT MOVEMENT ISOLATES CYANOBACTERIA
Nola de Chazal and GEOFF SMITH have developed a quick and powerful method for
isolating cyanobacteria (Appl Environ Microbiol (1992) 58:3561-3566). It is
based on the variable light-dependency of movement of cyanobacteria on scored
agar plates or through an agar overlay. They have used this method to isolate
a number of organisms from the hot desert region of Australia and from
tropical Indonesia. Interestingly, many of the organisms isolated in
Indonesia were brown whereas all organisms isolated from the desert area of
Australia were blue-green. Amongst the organisms isolated from Indonesia is
an interesting Synechocystis that is an alkalinophile, rendered uni-algal by
growth in high bicarbonate at pH 10. They have also isolated apparently
endolithic cyanobacteria from shell valves from two shell mounds on the Cape
York peninsula of Australia. The shell valves, when examined microscopically,
showed microborings on the interior surface. Cyanobacteria were found from
all genera, including Synechocystis, Dermocarpa, Xenococcus, Myxosarcina,
Chroococcidiopsis, Pleurocapsa, LPP group B, Anabaena, Nostoc, Scytonema, and
Fischerella. All of these were blue-green.
PHYLOGENETIC INFERENCES CONCERNING PROCHLOROPHYTES QUESTIONED
As described in the February 1992 issue of CyanoNews, most of the analyses
published so far of sequences from prochlorophytes suggest that they do not
share common ancestry with chloroplasts to the exclusion of cyanobacteria,
i.e., that they do not represent the "chloroplast ancestor". CHRIS HOWE warns
that the results of the analyses should be treated with some caution, because
the data violates an important (although not always explicit) assumption of
phylogenetic inference techniques: that base composition remains constant
over time. This assumption is clearly not valid, as chloroplast genomes have
a higher AT-bias than prochlorophytes and cyanobacteria. A consequence of
this violation is that sequences with similar bias in base composition will
group artificially closely in phylogenetic trees, and sequences with
different bias will be grouped further apart. One might therefore expect
prochlorophytes to be placed further from chloroplasts than actual
evolutionary relationships would dictate.
Work done by Howe in collaboration with colleagues in Sydney and elsewhere
[Lockhart PJ et al (1992), J Mol Evol 34:153-162] suggests that this
phenomenon may have misled analysis of the evolutionary position of the
cyanelle of Cyanophora paradoxa. Like chloroplasts, this organelle has a
highly AT-biased genome. Phylogenetic inference groups it with chloroplasts,
unless the least biased codon positions of the least biased genes are used,
in which case it is grouped with cyanobacteria. The apparent paradox points
out that one should check carefully to see if sequence data fits the
assumptions of the analytical techniques before relying on their conclusions.
IMMOBILIZING RECALCITRANT STRAIN IN CALCIUM ALGINATE
PAUL P. JACKSON and BRIAN WHITTON were trying to immobilize a strain of
Synechococcus (D562) that was isolated from a mine tailings pond in Missouri,
because of its possible use in removing cadmium from effluents. They found
that a range of cyanobacteria were able to grow immobilized in calcium
alginate beads, but not Synechococcus D562 (wouldn't you know it). They
solved the problem by supplementing sodium alginate with 5 mM KCl before the
addition of the cell suspension and subsequent transfer of the droplets of
this mixture to calcium chloride. It may be that adding KCl works with
Synechococcus D562 because of the relatively high K:Na ratio (1.2 to 1 on a
molar basis) found in water at the site from which the strain was isolated.
Even so, they recommend the use of KCl to anyone having difficulties
immobilizing a cyanobacterium in calcium alginate.
KEY NITROGEN REGULATOR IN ANABAENA FOUND TWICE?
Two groups, J.E. Frias, I. Luque, A. Merida, Antonia Herrero, and ENRIQUE
FLORES (Universidad de Sevilla) on one hand and T.S. Ramasubramanian, Tai-Fen
Wei, and JIM GOLDEN (Texas A&M University) on the other, appear to have both
cloned a gene from Anabaena PCC 7120 important in mediating the regulation
of genes in response to nitrogen status. The Sevilla group cloned the gene
by its homology to ntcA, a gene from Synechococcus PCC 7942 previously found
to be required for full expression several proteins subject to ammonium
repression [Vega-Palas MA et al (1992) Molec Microbiol 6:1853-1859]. The
Texas A&M group reached the same end from a study of a protein, called BifA
(formerly VF1), found in extracts of vegetative cells of Anabaena PCC 7120
and known to bind to regions upstream from glnA (encoding glutamine
synthetase) and other genes [Chastain CJ et al (1990) J Bacteriol
172:5044-5051]. A clone of the gene encoding BifA was selected by making use
of the ability of BifA to bind in E. coli to the glnA upstream region.
Both groups sequenced the gene and found it to be about 77% similar in
sequence to ntcA. The proteins deduced from the two genes (and from a third
homologous gene from Synechocystis PCC 6803 sequenced by the Sevilla group)
are all similar to members of a family of regulatory proteins typified by
Crp, a protein of E. coli involved in catabolite repression. Most striking,
the three deduced proteins share identical helix-turn-helix motifs, which
have been implicated in the binding of protein to DNA. Indeed, NtcA, like
BifA, was shown to bind to the regulatory region of glnA. The consensus
binding site of BifA is now known to be TGT(N)9-10ACA, the same as that of Crp
and NifA (a protein that regulates nitrogenase genes in Klebsiella and some
other nitrogen-fixing bacteria).
If BifA truly regulates the response of Anabaena to nitrogen deprivation,
then mutants defective in bifA (like already known mutants of Synechococcus
defective in ntcA) should show aberrant responses to changes in the source
of nitrogen. Preliminary evidence indicates that bifA mutants, like ntcA
mutants, cannot utilize nitrate as a nitrogen source.
