The kinetic behavior of xanthine oxidase containing chemically modified flavins.

Abstract

The steady-state and rapid kinetic properties of xanthine oxidase containing a series of FAD analogs of varying reduction potential have been investigated. From steady-state analysis, Vmax is found to exhibit a sigmoidal dependence on the flavin midpoint potential in the homologous series. This dependence is accurately described by a model in which the rate… (More)
