C-Terminal mutations in the chloroplast ATP synthase gamma subunit impair ATP synthesis and stimulate ATP hydrolysis.

Abstract excerpt

Two highly conserved amino acid residues, an arginine and a glutamine, located near the C-terminal end of the gamma subunit, form a "catch" by hydrogen bonding with residues in an anionic loop on one of the three catalytic beta subunits of the bovine mitochondrial F1-ATPase [Abrahams, J. P., Leslie, A. G., Lutter, R., and Walker, J. E. (1994) Nature 370, 621-628]. The catch is considered to play a critical role...
