The kinetic parameters for phenacetin O-deethylation by wild-type CYP1A2 and 19 variants were calculated.These values are shown in Table 1.The kinetic parameters K m, V max, CL int of CYP1A2.1 were 32.7 ± 0.7 μM, 6.57 ± 0.04 pmol/min/pmol CYP1A2, and 0.201 ± 0.005 μL/min/pmol CYP1A2, respectively. Epub 2003 Oct 16. In the reduced CO difference spectral analysis using recombinant proteins produced in the Sf21/baculovirus system, the peak at 450 nm seen in the WT protein was hardly observed in the three variants, suggesting marked reductions in their hemoprotein formation. CYP1A2*1E. The 5HTTLPR-relevant regions within SLC6A4 and the 102T>C allele of HTR2A were amplified using PCR. All three variant enzymes showed reduced protein expression levels (66% for Pro42Arg and approximately 30% for Arg377Gln and Arg456His) compared with that of the wild type (WT) without any change in mRNA expression levels.
