Research Abstract |
Poly-γ-glutamate hydrolase P (PghP) of Bacillus subtilis bacteriophage ΦNIT1 hydrolyzes the γ-glutamyl peptide linkage of extracellular poly-γ-glutamate produced by bacilli. Crystal structure of PghP was determined at a resolution of 1.9 A. Structure of PghP was elucidated as a globular protein with an open α/β mixed core structure and a seven-stranded parallel/anti-parallel β-sheet. Structure analysis demonstrated that PghP had a catalytic center containing a zinc ion and an overall topology resembling mammalian carboxypeptidase A and related enzymes.
