Abstract

The conservation and duplication of the tuf gene encoding the elongation factor EF-Tu were used to define phylogenetic relationships among eubacteria. When the tufA gene of Escherichia coli was used as a probe in hybridization experiments, duplicate tuf genes were found in gram-negative bacteria from three major phyla: purple bacteria, bacteroides, and cyanobacteria. Only a single copy of tuf was found in gram-positive bacteria, including mycobacteria and mycoplasmas. Gram-positive clostridia were found to carry two copies of tuf.

摘要

编码延伸因子EF-Tu的tuf基因的保守性和复制情况被用于确定真细菌之间的系统发育关系。当在杂交实验中使用大肠杆菌的tufA基因作为探针时，在三个主要门类的革兰氏阴性菌中发现了重复的tuf基因：紫色细菌、拟杆菌和蓝细菌。在革兰氏阳性菌中仅发现了一个tuf拷贝，包括分枝杆菌和支原体。革兰氏阳性梭菌被发现携带两个tuf拷贝。
