1 Furthermore, CYP2C9 produced by cDNA expression in yeasts, catalysed tolbutamide hydroxylation at rates similar to the rapid metabolizer group at both the 0.1 mM and 2.4 mM concentrations. Tolbutamide cytochrome P450 family 2 subfamily C member 9 Homo sapiens
2 Clear correlations were observed between the rate of microsomal tolbutamide hydroxylation at 0.1 mM and CYP2C9 protein content or the rate of S-mephenytoin 4"-hydroxylation in human liver. Tolbutamide cytochrome P450 family 2 subfamily C member 9 Homo sapiens
3 These results indicate that considerable portions of microsomal tolbutamide hydroxylation are catalysed by CYP2C9 or the closely related form in the rapid metabolizers. Tolbutamide cytochrome P450 family 2 subfamily C member 9 Homo sapiens
