Staphylococcal SplB serine protease utilizes a novel molecular mechanism of activation.
J. Biol. Chem. 289, 15544-15553 (2014)
Background: Activation of SplB protease requires precise N-terminal processing, but the molecular mechanism remains unknown. Results: The new N-terminal Glu-1 forms a distinctive H-bond network essential for full catalytic activity. Conclusion: Changes in protein dynamics rather than a direct effect on the active site are of crucial importance in SplB activation. Significance: A novel serine protease activation mechanism was uncovered.
