Immunochemical studies and complete amino acid sequence of the streptokinase from Streptococcus pyogenes (group A) M type 12 strain A374.
The complete amino acid sequence of the streptokinase (SKase) of Streptococcus pyogenes M type 12 strain A374, isolated from a patient with poststreptococcal glomerulonephritis (PSGN), was determined. The epitope domain for the monoclonal antibody N-59, which cross-reacts with SKases of both the PSGN-associated strain and S. equisimilis H46A (a non-PSGN-associated strain), was predicted to be localized in residues 370 to 374. The epitope domain specific for monoclonal antibody RU-1, which reacts only with the PSGN-associated SKase, was localized to residues 164 to 236.
