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

The green alga Chlamydomonas reinhardtii is a model organism for the study of photosynthesis. The chloroplast ATP synthase is responsible for the synthesis of ATP during photosynthesis. Using genetic engineering and biolistic transformation, a string

Oxidized ATP synthase of spinach thylakoid membranes catalyzes high rates of ATP synthesis in the light, but very low rates of ATP hydrolysis in the dark. Reduction of the disulfide bond in the gamma subunit of the ATP synthase in the light enhances

In contrast to everted mitochondrial inner membrane vesicles and eubacterial plasma membrane vesicles, the ATPase activity of chloroplast ATP synthase in thylakoid membranes is extremely low. Several treatments of thylakoids that unmask ATPase activi

The initial rate of Cu2+ movement across the thylakoid membrane of pea (Pisum sativum) chloroplasts was directly measured by stopped-flow spectrofluorometry using membranes loaded with the Cu2+-sensitive fluorophore Phen Green SK. Cu2+ transport was

The ATP synthases from chloroplasts and Escherichia coli are regulated by several factors, one of which is the epsilon subunit. This small subunit is also required for ATP synthesis. Thylakoid membranes reconstituted with CF1 lacking the epsilon subu

The intrinsic fluorescence of the catalytic portion of the chloroplast ATP synthase (CF1) is quenched when cysteine 322, the penultimate amino acid of the gamma subunit, is specifically labeled with pyrene maleimide (PM). The epsilon subunit of CF1 c

Electron transport and the electrochemical proton gradient across the thylakoid membrane are two fundamental parameters of photosynthesis. A combination of the electron acceptor, ferricyanide and the ΔpH indicator, 9-aminoacridine, was used to measu

The chloroplast ATP synthase is strictly regulated so that it is very active in the light (rates of ATP synthesis can be higher than 5 micromol/min/mg protein), but virtually inactive in the dark. The subunits of the catalytic portion of the ATP synt
