Bile acid-CoA: amino acid N-acyltransferase (BAAT) is a key enzyme in bile acid metabolism, primarily responsible for catalyzing the conjugation of bile acids with amino acids such as taurine or glycine. This process enhances the water solubility and detoxification of bile acids, critical for their role in lipid digestion and cholesterol homeostasis. BAAT is expressed predominantly in the liver, where it localizes to the cytoplasm and peroxisomes. The enzyme functions in the final step of the bile acid biosynthesis pathway, enabling the secretion of conjugated bile acids into bile for intestinal absorption and enterohepatic recirculation.
Deficiencies or mutations in BAAT are linked to metabolic disorders, notably familial hypercholanidemia (FHCA), characterized by elevated serum bile acids, growth retardation, and vitamin deficiencies. Studies using BAAT-knockout models highlight its essential role in maintaining bile acid homeostasis and preventing hepatotoxicity. Recombinant BAAT (rBAAT) has been engineered for research applications, facilitating mechanistic studies of bile acid conjugation and therapeutic exploration for liver-related metabolic diseases. Its structure-function relationships and regulatory mechanisms remain active areas of investigation, with implications for understanding cholestasis, fatty liver disease, and bile acid signaling pathways.
