Protein attributes
| Sequence length | 494 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Highly active in the 15-alpha-hydroxylation of testosterone. Also active in the 15-alpha-hydroxylation of progesterone and androstenedione. Little or no activity on corticosterone, pregnenolone, dehydroepiandrosterone, estradiol or estriol. |
| Catalytic activity | RH + reduced flavoprotein + O2 = ROH + oxidized flavoprotein + H2O. |
| Cofactor | Heme group By similarity. |
| Subcellular location | Endoplasmic reticulum membrane; Peripheral membrane protein. Microsome membrane; Peripheral membrane protein. |
| Tissue specificity | Kidney and lung. Expressed in liver, with a strong circadian rhythmicity. Circadian expression is regulated by DBP. Ref.6 |
| Miscellaneous | There are only 11 differences between the sequence of testosterone 15-alpha-hydroxylase and that of coumarin 7-hydroxylase. By site-directed mutagenesis it has been shown that modification of position 209 is sufficient to convert the specificity of the two forms of the enzyme. |
| Sequence similarities | Belongs to the cytochrome P450 family. |
