摘要：

The genes encoding the beta-subunit of adenosine triphosphate synthase of two gram-positive bacteria with a low DNA G + C content, Pectinatus frisingensis and Lactobacillus casei, were cloned and sequenced. The predicted amino acid sequences were compared with 29 homologous sequences of (eu)bacteria. Most of the putative functional amino acid residues are conserved in the molecules investigated. A subunit composition resembling that of F1F0 ATPase complexes from respiring bacateria was found in the case of Pectinatus frisingensis. A phylogenetic analysis revealed closer relationship of Lactobacillus casei and bacilli, whereas Pectinatus frisingensis is only moderately related to the former organisms and to mycoplasmas as previously seen by 16S rRNA analysis.
