== Publication Abstract from PubMed ==
 +
Serine proteinase catalyzed peptide splicing was demonstrated in both, one and two-peptide-chain (C- and N-terminal peptide chains linked by a disulfide bridge) trypsin inhibitor SFTI-1 analogues. In the second series, peptide splicing, with catalytic amount of proteinase, was observed only when formation of acyl-enzyme intermediate was preceded by the hydrolysis of the substrate Lys-Ser peptide bond. Here we presented that at an equimolar amount of the proteinase, splicing occurred in all two-peptide-chain analogues. This conclusion was supported by high resolution crystal structures of selected analogues in complex with trypsin. We showed that the process followed a direct transpeptidation mechanism. It means that the acyl-enzyme intermediate was formed and was immediately utilized for a new peptide bond formation, and products associated with the hydrolysis of acyl-enzyme were not observed. The demonstrated peptide splicing was a sequence- not structure-specific.
