This model describes acetate-CoA ligase (EC 6.2.1.1), also called acetyl-CoA synthetase and acetyl-activating enzyme. It catalyzes the reaction ATP + acetate + CoA = AMP + diphosphate + acetyl-CoA and belongs to the family of AMP-binding enzymes described by pfam00501. Length = 625
>gnl|CDD|213313 cd05966, ACS, Acetyl-CoA synthetase (also known as acetate-CoA ligase and acetyl-activating enzyme)
Acetyl-CoA synthetase (ACS) catalyzes the formation of acetyl-CoA from acetate, CoA, and ATP. Synthesis of acetyl-CoA is carried out in a two-step reaction. In the first step, the enzyme catalyzes the synthesis of acetyl-AMP intermediate from acetate and ATP. In the second step, acetyl-AMP reacts with CoA to produce acetyl-CoA. This enzyme is widely present in all living organisms. The activity of this enzyme is crucial for maintaining the required levels of acetyl-CoA, a key intermediate in many important biosynthetic and catabolic processes. Acetyl-CoA is used in the biosynthesis of glucose, fatty acids, and cholesterol. It can also be used in the production of energy in the citric acid cycle. Eukaryotes typically have two isoforms of acetyl-CoA synthetase, a cytosolic form involved in biosynthetic processes and a mitochondrial form primarily involved in energy generation. Length = 602
This family contains one of three readily separable clades of proteins in the group of acetate and propionate--CoA ligases. Characterized members of this family act on propionate. From propionyl-CoA, there is a cyclic degradation pathway: it is ligated by PrpC to the TCA cycle intermediate oxaloacetate, acted upon further by PrpD and an aconitase, then cleaved by PrpB to pyruvate and the TCA cycle intermediate succinate.
This enzyme catalyzes the first step of the mevalonate pathway of IPP biosynthesis. Most bacteria do not use this pathway, but rather the deoxyxylulose pathway.
