Structural and functional analysis of the phosphoenolpyruvate carboxylase gene from the purple nonsulfur bacterium Rhodopseudomonas palustris No. 7.

Abstract

The ppc gene, encoding phosphoenolpyruvate carboxylase (PEPC), from Rhodopseudomonas palustris No. 7 was cloned and sequenced. Primer extension analysis identified a transcriptional start site 42 bp upstream of the ppc initiation codon. An R. palustris No. 7 PEPC-deficient strain showed a slower doubling time compared with the wild-type strain either anaerobically in the light or aerobically in the dark, when pyruvate was used as a carbon source.
