GO:0008390 testosterone 16-alpha-hydroxylase activity with no cross reference

[raymond91125]

GO:0008390 testosterone 16-alpha-hydroxylase activity lacks EC/RHEA cross references.
There is no publication reference but narrow synonyms cytochrome P450 CPY2B10, 2B9, 2D10, 2D11, 2D9. In UniProt, these are all annotated to EC:1.14.14.1 unspecific monooxygenase.
Looking at annotations to GO:0008390, like human CPY2B6 at UniProt. There is a match
RHEA:53196 O2 + reduced [NADPH--hemoprotein reductase] + testosterone = 16alpha,17beta-dihydroxyandrost-4-en-3-one + H(+) + H2O + oxidized [NADPH--hemoprotein reductase].
