- PubMed Abstract:
Thiolases are ubiquitous and form a large family of dimeric or tetrameric enzymes with a conserved, five-layered alphabetaalphabetaalpha catalytic domain. Thiolases can function either degradatively, in the beta-oxidation pathway of fatty acids, or biosynthetically. Biosynthetic thiolases catalyze the biological Claisen condensation of two molecules of acetyl-CoA to form acetoacetyl-CoA. This is one of the fundamental categories of carbon skeletal assembly patterns in biological systems and is the first step in a wide range of biosynthetic pathways, including those that generate cholesterol, steroid hormones, and various energy-storage molecules.
