The nucleotide sequences of the Enterobacter aerogenes and Klebsiella pneumoniae DNA replication origins (oriC) were determined and compared with those of Escherichia coli and Salmonella typhimurium. Four interrelated, 9-base-pair repeats were identified from the conserved regions within the minimal origin. Evolutionary rates calculated from the minimal origin sequences yielded a quantitative phylogenic tree which agreed with the taxonomic classification of these genera.
测定了产气肠杆菌和肺炎克雷伯菌DNA复制起点(oriC)的核苷酸序列,并与大肠杆菌和鼠伤寒沙门氏菌的进行了比较。从最小起点内的保守区域中鉴定出四个相互关联的9碱基对重复序列。根据最小起点序列计算的进化速率产生了一棵定量系统发育树,该树与这些属的分类学分类一致。
