摘要	F-type ATP synthases produce nearly all of the ATP found in cells. The catalytic module F-1 commonly comprises an a alpha(3)beta(3) hexamer surrounding a gamma/epsilon stalk. However, it is unclear how these subunits assemble to form a catalytic motor. In this work, we identified and characterized a chloroplast protein that interacts with the CF1 beta, gamma, and epsilon subunits of the chloroplast ATP synthase and is required for assembly of its F-1 module. We named this protein BIOGENESIS FACTOR REQUIRED FOR ATP SYNTHASE1 (BFA1) and determined its crystal structure at 2.8-angstrom resolution. BFA1 is comprised primarily of two interacting beta-barrels that are oriented nearly perpendicularly to each other. The contact region between BFA1 and the CF1 beta and gamma subunits was further mapped by yeast two-hybrid assays. An in silico molecular docking analysis was performed and revealed close fitting contact sites without steric conflicts between BFA1 and CF1 beta/gamma. We propose that BFA1 acts mainly as a scaffold protein promoting the association of a CF1 alpha/beta heterodimer with CF1 gamma. The subsequent assembly of other CF1 alpha/beta heterodimers may shift the position of the CF1 gamma. subunit to complete assembly of the CF1 module. This CF1 assembly process is likely to be valid for other F-type ATP synthases, as their structures are highly conserved.
