Protein Family Models

Part of the ATP synthase CF(1). These subunits are part of the head unit of the ATP synthase. The subunit is called epsilon in bacteria and delta in mitochondria. In bacteria the delta (D) subunit is equivalent to the mitochondrial Oligomycin sensitive subunit, OSCP (Pfam:PF00213). [1]. 9331422.

This HMM describes one of the five types of subunits in the F1 part of F1/F0 ATP synthases. Members of this family are designated epsilon in bacterial and chloroplast systems but designated delta in mitochondria, where the counterpart of the bacterial delta subunit is designated OSCP. In a few cases (Propionigenium modestum, Acetobacterium woodii) scoring above the trusted cutoff and designated here as exceptions, Na+ replaces H+ for translocation.

The FoF1 ATP synthase subunit delta/epsilon is a component of the F1-complex catalytic core of the F-type ATPase, which synthesizes ATP from ADP in the presence of a proton gradient across the membrane
