Tag Archives: pyrophosphate

A coenzyme and one of the most impor­tant compounds in the metabolism of all organisms, since it serves as a coupling agent between different enzymatic reactions. Adenosine triphosphate is adenosine diphos­phate (ADP) with an additional phosphate group attached through a pyrophosphate linkage to the terminal phosphate group (see illustration). ATP is a powerful donor of phosphate groups to suitable acceptors …

acetate–CoA ligase EC 6.2.1.1; systematic name: acetate:CoA ligase (AMP-forming); other names: acetyl–CoA synthetase; acyl-activating enzyme; acetate thiokinase; acetyl-activating enzyme. An enzyme that catalyses a reaction between ATP, acetate, and CoA to form AMP, pyrophosphate, and acetyl-CoA. It is an important enzyme in organisms (e.g. Escherichia coli, many fungi, protozoans, algae) that utilize acetate as a carbon source. Distinguish from acetate– …
