atpB — Beta vulgaris subsp. vulgaris

Summary

BVRB_4G094910 (atpB) on sugar beet chromosome Bvchr4_un.sca015 encodes a beta subunit of the H+-transporting two-sector ATPase, belonging to the ATPase alpha/beta chain family and possessing proton-transporting ATP synthase activity with a rotational mechanism as well as ATP binding. The gene is associated with proton motive force-driven mitochondrial ATP synthesis, phosphoglyceride metabolism, inositol phosphate metabolism, tRNA charging, phosphate metabolism, and glutathione metabolism. Its product localises to the F1-F0 complex, chloroplast thylakoid membrane, and mitochondria. Related genes in other species link the family to mitochondrial and chloroplast ATP production.
