Effects of added protein (bovine serum albumin) on the rate and enantiotopic selectivity of oxidative O-demethylation of methoxychlor in rat liver microsomes
1991
Kurihara, N. | Oku, A.
The addition of bovine serum albumin (BSA) to rat liver microsomal suspensions during the O-demethylation of methoxychlor (1,1-bis(4-methoxyphenyl)-2,2,2-trichloroethane) produced a good substrate concentration-reaction rate relationship, and allowed us to determine the rate parameters for this reaction. The apparent Km became larger when the albumin content was increased, whereas Vmax was not changed. The enantiotopic selectivity of the reaction dramatically changed when the substrate concentration was increased in the absence of BSA in phenobarbital-treated rat liver microsomes.
