The gltBY locus of E. coli, which codes for the two subunits of pyridine nucleotide dependent glutamate synthase, was used as a probe to detect homologues in genomic DNA of Synechococcus PCC6301, a unicellular cyanobacterium. Non-overlapping probes from gltB detected a single homologue with extensive homology, however gltY probes do not detect a strong homologue. The possibility that the gltB homologue encodes a ferredoxin-dependent glutamate synthase of the type found in cyanobacteria, algae and plants is discussed.
