The phbC (poly-beta-hydroxybutyrate synthase) gene of Rhizobium (Sinorhizobium) meliloti and characterization of phbC mutants.

L B Willis1, G C Walker.   

Abstract

Defined insertion mutations have been constructed in the Rhizobium (Sinorhizobium) meliloti phbC gene, which encodes poly-beta-hydroxybutyrate (PHB) synthase. The locus was isolated and subcloned from a genomic library of R. meliloti Rm1021 by complementation of phbC mutation of Alcaligenes eutrophus. PHB production was detected in wild-type R. meliloti under nutrient-limited conditions but not in rich medium. No PHB production was detected in the R. meliloti phbC mutants. The DNA sequence of the R. meliloti phbC gene was determined. The deduced polypeptide sequence is homologous to previously identified PhbCs from other bacteria. The R. meliloti phbC locus maps to pRmeSU47a, the smaller of the two megaplasmids in this strain.
