Zinc 9-15 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 215-224 15763633-6 2005 These results suggest that the inhibitory effects of Zn2+ come from preventing the stimulation of b5 on CYP3A4 activity. Zinc 53-57 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 104-110 15763633-1 2005 Effects of Zn2+ on the activity and conformation of cytochorome P450 3A4 (CYP3A4) were investigated. Zinc 11-15 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 52-72 15763633-1 2005 Effects of Zn2+ on the activity and conformation of cytochorome P450 3A4 (CYP3A4) were investigated. Zinc 11-15 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 74-80 15763633-2 2005 Zn2+ specifically inhibited the testosterone 6beta-hydroxylation activity of CYP3A4 with an IC50 value of 27 microM. Zinc 0-4 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 77-83 15763633-3 2005 Zn2+ inhibited the CO-binding spectra of CYP3A4 reduced by NADPH-cytochrome P450 reductase (CPR) and NADPH only in the presence of b5. Zinc 0-4 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 41-47 15763633-4 2005 Zn2+-induced conformational changes of CYP3A4 were monitored by CD and intrinsic fluorescence.
