THE CRYSTAL STRUCTURE OF MALONAMIDASE E2 COVALENTLY COMPLEXED WITH PYROPHOSPHATE FROM BRADYRHIZOBIUM JAPONICUM

Overview

A large group of hydrolytic enzymes, which contain a conserved stretch of, approximately 130 amino acids designated the amidase signature (AS), sequence, constitutes a super family that is distinct from any other known, hydrolase family. AS family enzymes are widespread in nature, ranging from, bacteria to humans, and exhibit a variety of biological functions. Here we, report the first structure of an AS family enzyme provided by the crystal, structure of malonamidase E2 from Bradyrhizobium japonicum. The structure, representing a new protein fold, reveals a previously unidentified, Ser-cisSer-Lys catalytic machinery that is absolutely conserved throughout, the family. This family of enzymes appears to be evolutionarily distinct, but has diverged to acquire a wide spectrum of individual ... [(full description)]
