Serine 74-80 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 6-24 20160131-4 2010 One factor favoring more efficient electron transfer and 17,20 lyase activity is cAMP-dependent serine/threonine phosphorylation of P450c17. Serine 96-102 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 132-139 20160131-8 2010 Using this vector, we explored P450c17 phosphorylation by mutagenesis of Ser and/or Thr residues to Asp or Glu to mimic the approximate size and charge of phospho-Ser or phospho-Thr. Serine 73-76 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 31-38
