ATP synthase F1, delta subunit; 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.

50S ribosomal protein L13; This protein is one of the early assembly proteins of the 50S ribosomal subunit, although it is not seen to bind rRNA by itself. It is important during the early stages of 50S assembly.

Elongation factor P; Involved in peptide bond synthesis. Stimulates efficient translation and peptide-bond synthesis on native or reconstituted 70S ribosomes in vitro. Probably functions indirectly by altering the affinity of the ribosome for aminoacyl-tRNA, thus increasing their reactivity as acceptors for peptidyl transferase.

ATP synthase gamma chain; 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.

Hypothetical protein.

30S ribosomal protein S10; Involved in the binding of tRNA to the ribosomes. Belongs to the universal ribosomal protein uS10 family.

30S ribosomal protein S2; Belongs to the universal ribosomal protein uS2 family.

V-type ATPase, D subunit; Produces ATP from ADP in the presence of a proton gradient across the membrane.

V-type H+-transporting ATPase subunit B; Produces ATP from ADP in the presence of a proton gradient across the membrane. The V-type beta chain is a regulatory subunit.
