Abstract
Pz peptidase B is an intracellular M3 metallopeptidase that is found together with Pz peptidase A in the thermophile Geobacillus collagenovorans MO-1 and recognizes collagen-specific tripeptide units (-Gly-Pro-X-). These peptidases have low homology in their primary structures; however, their cleavage patterns towards peptide substrates are similar. In this work, Pz peptidase B was crystallized using the counter-diffusion method. Data were collected to a resolution of 1.6 Å at 100 K from a crystal obtained in the Japanese Experiment Module (JEM; also known as `Kibo') at the International Space Station (ISS). The crystal belonged to the trigonal space group P3(1)21, with unit-cell parameters a = b = 87.64, c = 210.5 Å. A complete data set was also obtained from crystals of selenomethionine-substituted protein.

Kawasaki A, Nakano H, Hosokawa A, Nakatsu T, Kato H, Watanabe K. The exquisite structure and reaction mechanism of bacterial Pz-peptidase A toward collagenous peptides: X-ray crystallographic structure analysis of PZ-peptidase a reveals differences from mammalian thimet oligopeptidase. J Biol Chem 2010; 285:34972-80. [PMID: 20817732 PMCID: PMC2966111 DOI: 10.1074/jbc.m110.141838] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2010] [Revised: 06/30/2010] [Indexed: 11/06/2022] Open
Abstract
Pz-peptidase A, from the thermophilic bacterium Geobacillus collagenovorans MO-1, hydrolyzes a synthetic peptide substrate, 4-phenylazobenzyloxycarbonyl-Pro-Leu-Gly-Pro-D-Arg (Pz-PLGPR), which contains a collagen-specific tripeptide sequence, -Gly-Pro-X-, but does not act on collagen proteins themselves. The mammalian enzyme, thimet oligopeptidase (TOP), which has comparable functions with bacterial Pz-peptidases but limited identity at the primary sequence level, has recently been subjected to x-ray crystallographic analysis; however, no crystal structure has yet been reported for complexes of TOP with substrate analogues. Here, we report crystallization of recombinant Pz-peptidase A in complex with two phosphinic peptide inhibitors (PPIs) that also function as inhibitors of TOP and determination of the crystal structure of these complexes at 1.80-2.00 Å resolution. The most striking difference between Pz-peptidase A and TOP is that there is no channel running the length of bacterial protein. Whereas the structure of TOP resembles an open bivalve, that of Pz-peptidase A is closed and globular. This suggests that collagenous peptide substrates enter the tunnel at the top gateway of the closed Pz-peptidase A molecule, and reactant peptides are released from the bottom gateway after cleavage at the active site located in the center of the tunnel. One of the two PPIs, PPI-2, which contains the collagen-specific sequence, helped to clarify the exquisite structure and reaction mechanism of Pz-peptidase A toward collagenous peptides. This study describes the mode of substrate binding and its implication for the mammalian enzymes.
