Background
Recombinant Trypsin (rTrypsin) is a genetically engineered serine protease (EC 3.4.21.4) produced via recombinant DNA technology, most commonly in microbial host systems such as Pichia pastoris or E. coli, to yield an enzyme that is identical in amino acid sequence to native porcine or bovine trypsin while ensuring an animal-free production process free from contaminants like chymotrypsin and risks of viral or transmissible spongiform encephalopathy (TSE) agents. As a key biocatalyst, it specifically hydrolyzes peptide bonds at the carboxyl termini of lysine and arginine residues, a specificity determined by its conserved catalytic triad (His57, Asp102, Ser195) and the substrate-binding S1 pocket, with its structural integrity maintained by a calcium-binding loop.
