Tyrosinase kinetic analysis

Kinetic analysis of tyrosinase and calculation of constants will be described using graphical analysis by the Michaelis-Menten equation, Lineweaver-Burk equation, or the direct linear curve. Procedures for preparing these graphs are described below. Alternatively, students may use available computer software to graph data and calculate kinetic constants. Recommended enzyme kinetic computer software packages include Enzyme... [Pg.297]

Oxidative decarboxylation of 3,4-dihydroxymandelic acid (DHMA) to 3,4-dihydroxybenzaldehyde (DHBald) is also catalyzed by tyrosinase [245-251]. At first a direct oxidative decarboxylation to quinone methide was proposed [245]. Later, the reaction through the quinone intermediate was proposed based on the spectroscopic detection of the intermediate and the kinetic analysis as shown in Scheme 13 [246, 248]. The mechanism was supported by the fact that nearly 90% deuterium retains in the formation of 3,4-dihydroxybenzaldehyde from deuterated 3,4-dihydroxymandelic acid [251]. [Pg.330]
