Abstract: Recent developments on protein engineering of some related proteins in our research are introduced. Specificity change, antiautolysis and role of less conserved disulfide bonds of trypsin are demonstrated. Function of single domain and multi-copied domains of metallothionein is explained. Studies on intra-A chain disulfide bond and C-peptide of insulin, chimera of prourokinase and tissue-type plasminogen activator, mutation of plasminogen activator inhibitor-1, and RGD-containing proteins are also described.

Key words: protein engineering, trypsin, metallothionein, insulin, antithrombotics, protein structure and function, mutant protein, protein engineering, trypsin, metallothionein, insulin, antithrombotics, protein structure and function, mutant protein
