ATP synthase F0F1 subunit A; Key component of the proton channel; it plays a direct role in the translocation of protons across the membrane. Belongs to the ATPase A chain family.

ATP synthase F0F1 subunit B; Component of the F(0) channel, it forms part of the peripheral stalk, linking F(1) to F(0); Belongs to the ATPase B chain family.

ATP synthase F0F1 subunit delta; F(1)F(0) ATP synthase produces ATP from ADP in the presence of a proton or sodium gradient. F-type ATPases consist of two structural domains, F(1) containing the extramembraneous catalytic core and F(0) containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation.

ATP synthase subunit alpha; Produces ATP from ADP in the presence of a proton gradient across the membrane. The alpha chain is a regulatory subunit.

ATP synthase F0F1 subunit gamma; Produces ATP from ADP in the presence of a proton gradient across the membrane. The gamma chain is believed to be important in regulating ATPase activity and the flow of protons through the CF(0) complex.

ATP synthase subunit beta; Produces ATP from ADP in the presence of a proton gradient across the membrane. The catalytic sites are hosted primarily by the beta subunits.

ATP synthase subunit epsilon; Produces ATP from ADP in the presence of a proton gradient across the membrane.

Polyketide synthase; Derived by automated computational analysis using gene prediction method: Protein Homology.

Preprotein translocase YidC; Functions to insert inner membrane proteins into the IM in Escherichia coli; interacts with transmembrane segments; functions in both Sec-dependent and -independent membrane insertion; similar to Oxa1p in mitochondria; Derived by automated computational analysis using gene prediction method: Protein Homology.
