Previous studies have not provided definitive information about whether ADP or Pi or their complexes with Mg2+ serve as substrates for photophosphorylation and whether free Mg2+ or ADP is required. Results presented show MgADP, MgGDP, or MgUDP are substrates. At variable Mg2+ concentrations, observed velocities are determined by MgADP and not the free ADP… CONTINUE READING
