Description (originally from EcoCyc[1][2]) ATP synthase
Comments (originally from EcoCyc[1][2]) ATP synthase catalyzes the synthesis of ATP under aerobic cell growth. The energy derived from oxygen respiration is coupled to ATP synthesis by a process known as electron transport-linked phosphorylation. Under anaerobic growth conditions an electrochemical proton gradient can also be generated using a number of alternative electron acceptors and ATP synthase can also synthesize ATP under these conditions. During fermentation however, ATP is synthesized only by substrate-level phosphorylation reactions. ATP synthase catalyzes the hydrolysis of ATP under these conditions to generate the electrochemical proton gradient needed for other membrane functions. [3][4][5]
