Enzymes

General function:
Involved in catalytic activity
Specific function:
Catalyzes the esterification, concomitant with transport, of exogenous fatty acids into metabolically active CoA thioesters for subsequent degradation or incorporation into phospholipids. It has a low activity on medium or long chain fatty acids and is maximally active on C6 and C8 substrates
Gene Name:
fadK
Uniprot ID:
P38135
Molecular weight:
60773
Reactions
ATP + a short-chain carboxylic acid + CoA = AMP + diphosphate + an acyl-CoA.
