Amino acid sequence comparison of Grimontia hollisae collagenase with homologous collagenase. (A) The amino acid sequences from G. hollisae (the present study), Vibrio parahaemolyticus (NP_797719), and Vibrio alginolyticus (CAA44501) were aligned by using the CLUSTAL W2 program. Identical residues among the three sequences are indicated by asterisks. (B) Schematic representation of the domain architecture of G. hollisae (the present study), V. parahaemolyticus (NP_797719) and V. alginolyticus (CAA44501). Pre, signal peptide; pro, putative pro-domain; PKD, polycystic kidney disease-like domain; PPC, pre-peptidase C-terminal domain.
