Extracellular glutamyl endopeptidase from Bacillus intermedius (BIEP) is a chymotrypsin-like serine protease which cleaves the peptide bond on the carboxyl side of glutamic acid. Its three-dimensional structure was determined for C222(1) and C2 crystal forms of BIEP to 1.5 and 1.75 A resolution, respectively. The topology of BIEP diverges from the most common chymotrypsin architecture, because one of the domains consists of a beta-sandwich consisting of two antiparallel beta-sheets and two helices. In the C2 crystals, a 2-methyl-2,4-pentanediol (MPD) molecule was found in the substrate binding site, mimicking a glutamic acid. This enabled the identification of the residues involved in the substrate recognition. The presence of the MPD molecule causes a change in the active site; the interaction between two catalytic residues (His47 and Ser171) is disrupted. The N-terminal end of the enzyme is involved in the formation of the substrate binding pocket. This indicates a direct relation between zymogen activation and substrate charge compensation. | |||

Publication Abstract from PubMedExtracellular glutamyl endopeptidase from Bacillus intermedius (BIEP) is a chymotrypsin-like serine protease which cleaves the peptide bond on the carboxyl side of glutamic acid. Its three-dimensional structure was determined for C222(1) and C2 crystal forms of BIEP to 1.5 and 1.75 A resolution, respectively. The topology of BIEP diverges from the most common chymotrypsin architecture, because one of the domains consists of a beta-sandwich consisting of two antiparallel beta-sheets and two helices. In the C2 crystals, a 2-methyl-2,4-pentanediol (MPD) molecule was found in the substrate binding site, mimicking a glutamic acid. This enabled the identification of the residues involved in the substrate recognition. The presence of the MPD molecule causes a change in the active site; the interaction between two catalytic residues (His47 and Ser171) is disrupted.
