TY - JOUR PY - 2010// TI - Studies of the competing rates of catechol oxidation and suicide inactivation of tyrosinase JO - Arkivoc A1 - Ramsden, C.A. A1 - Riley, P.A. SP - 248 EP - 254 VL - 2010 IS - 10 N2 - Tyrosinase oxidation of catechols to ortho-quinones is accompanied by suicide inactivation of the enzyme. The rates of these competing processes vary and depend on the nature of ring substituents. For a series of 4-substituted catechols the relationships between structure and reaction rates have been examined using multiple regression. Significant but different structure-rate relationships were found for each process. The oxidation rate (k1) is greatest for short hydrophobic substituents; there is an optimum substituent hydrophobicity (π ̃ 0.7) for the rate of inactivation (k2). © ARKAT USA, Inc.
