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.
克隆并测序了来自沼泽红假单胞菌7号菌株的ppc基因,该基因编码磷酸烯醇式丙酮酸羧化酶(PEPC)。引物延伸分析确定了ppc起始密码子上游42 bp处的一个转录起始位点。当以丙酮酸作为碳源时,沼泽红假单胞菌7号PEPC缺陷型菌株在光照厌氧条件下或黑暗需氧条件下,与野生型菌株相比,其倍增时间较慢。
