Figure 1From: Molecular cloning and characterization of a novel peptidase from Trichinella spiralis and protective immunity elicited by the peptidase in BALB/c micePhylogenetic tree consisting of peptidases from 11 organisms determined with the NJ method (A) and the predicted 3-dimensional structure of the TsP protein (B). Three serine protease-specific active site residues (His, Asp and Ser) in TsP are coloured red.Back to article page
