| 1 | Values of kinetic parameters for the hydrolysis of esters and p-nitroanilides of L-lysine and L-arginine catalyzed by the Lys77 form of human plasmin (EC 3.4.21.7) have been determined between pH 5.5 and 8 (I = 0.1 M) at 21 +/- 0.5 degrees C. Over the whole pH range explored, Lys77-plasmin catalysis conforms to simple Michaelis-Menten kinetics, and steady-state and pre-steady-state data may be consistently fitted to the minimum three-step mechanism: E + S in equilibrium (k+1/k-1)E X S----(k+2)E X P + P1----(k+3)E + P2 In spite of the higher specificity of lysyl derivatives for Lys77-plasmin rather than the arginyl ones, kinetic parameters also depend on the nature of the N-alpha substituent and/or of the alcoholic or p-nitroanilidic moiety of the substrate. | Esters | plasminogen | Homo sapiens |
