BIOSYNTHETIC THIOLASE FROM ZOOGLOEA RAMIGERA IN COMPLEX WITH A REACTION INTERMEDIATE.

Overview

BACKGROUND: 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. RESULTS: The crystal structure of the tetrameric, biosynthetic thiolase from Zoogloea ramigera has been determined at 2.0 ... [(full description)]
