A salt-sensitive mutant of Synechocystis sp. strain PCC 6803 defective in the synthesis of the compatible solute glucosylglycerol (GG) was used to search for the gene encoding GG-phosphate synthase (GGPS), the key enzyme in GG synthesis. Cloning and sequencing of the mutated region and the corresponding wild-type region revealed that a deletion of about 13 kb occurred in the genome of mutant 11. This deletion affected at least 10 open reading frames, among them regions coding for proteins showing similarities to trehalose (otsA homolog)- and glycerol-3-phosphate-synthesizing enzymes. After construction and characterization of mutants defective in these genes, it became obvious that an otsA homolog (sll1566) (T. Kaneko et al., DNA Res. 3:109-136, 1996) encodes GGPS, since only the mutant affected in sll1566 showed salt sensitivity combined with a complete absence of GG accumulation. Furthermore, the overexpression of sll1566 in Escherichia coli led to the appearance of GGPS activity in the heterologous host. The overexpressed protein did not show the salt dependence that is characteristic for the GGPS in crude protein extracts of Synechocystis. << Less
