the most interesting difference between the structures of rvv-v and other trypsin-type serine proteases is that the conservative ser214-trp215-gly216 sequence ( chymotrypsinogen numbering ) , considered as the site of antiparallel beta-sheet formation between the protein substrate and most serine proteases , has been replaced by the corresponding sequence ala-gly-gly .
