CRYSTAL STRUCTURE OF THE 2,6-DIHYDROXY-PSEUDO-OXYNICOTINE HYDROLASE.
Overview
The enzyme 2,6-dihydroxy-pseudo-oxynicotine hydrolase from the, nicotine-degradation pathway of Arthrobacter nicotinovorans was, crystallized and the structure was determined by an X-ray diffraction, analysis at 2.1 A resolution. The enzyme belongs to the, alpha/beta-hydrolase family as derived from the chain-fold and from the, presence of a catalytic triad with its oxyanion hole at the common, position. This relationship assigns a pocket lined by the catalytic triad, as the active center. The asymmetric unit contains two C(2)-symmetric, dimer molecules, each adopting a specific conformation. One dimer forms a, more spacious active center pocket and the other a smaller one, suggesting, an induced-fit. All of the currently established C-C bond cleaving, alpha/beta-hydrolases are from ...
