Abstract

This family represents subunits called delta (in mitochondrial ATPase) or epsilon (in bacteria or chloroplast ATPase). The interaction site of subunit C of the F0 complex with the delta or epsilon subunit of the F1 complex may be important for connecting the rotor of F1 (gamma subunit) to the rotor of F0 (C subunit) [PubMed12887009]. In bacterial species, the delta subunit is the equivalent of the Oligomycin sensitive subunit (OSCP, ) in metazoans. The C-terminal domain of the epsilon subunit appears to act as an inhibitor of ATPase activity [PubMed16707672].

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 3 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a Epsilon subunit of F1F0-ATP synthase C-terminal domain domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 3 hidden Markov models representing the Epsilon subunit of F1F0-ATP synthase C-terminal domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
