Formate is the major source of C1 units in many species of the genus Clostridium. In this study we have cloned and characterized the genes encoding pyruvate formate-lyase and its activating enzyme of Clostridium pasteurianum. The genetic and transcriptional organizations of the genes and the high level of homology exhibited by the respective gene products to their Escherichia coli counterparts indicate strong evolutionary conservation of these enzymes.
甲酸是许多梭菌属物种中一碳单位的主要来源。在本研究中,我们克隆并鉴定了巴氏梭菌中编码丙酮酸甲酸裂解酶及其激活酶的基因。这些基因的遗传和转录组织以及各自基因产物与其大肠杆菌对应物所表现出的高度同源性表明这些酶具有很强的进化保守性。
