The three genes (pduCDE) encoding the diol dehydratase of Lactobacillus collinoides were sequenced. They exhibited strong identities with the ddrABC and pduCDE genes of Klebsiella oxytoca and Salmonella enterica, respectively. These genes are part of a putative operon with at least four other genes. An eighth open reading frame was identified as homologous to the pocR gene (encoding the operon regulatory protein). Although the enzyme was detected in exponential growth phase, PduCDE activity was increased at the end of exponential phase in presence of 1,2-propanediol.
对编码柯氏乳杆菌二醇脱水酶的三个基因（pduCDE）进行了测序。它们分别与产酸克雷伯菌和肠炎沙门氏菌的ddrABC和pduCDE基因具有高度同源性。这些基因是一个推定操纵子的一部分，该操纵子至少还有其他四个基因。一个第八开放阅读框被鉴定为与pocR基因（编码操纵子调节蛋白）同源。尽管在指数生长期检测到了该酶，但在1,2 - 丙二醇存在的情况下，指数期末期PduCDE活性增加。
