The 3-dimensional structures of bovine chymotrypsin and bovine trypsin are one of the earliest fruitful achievements in the field of protein crystallography. In 1970, R. M. Stroud et al. disclosed the stereoscopic structure of bovine trypsin at 2.7 (?) resolution. In 1972, J. J. Birktoft et al. also reported the 3-dimensional structure of bovine
