CC -!- FUNCTION: A cytochrome P450 monooxygenase that catalyzes the omega-
CC hydroxylation of prostaglandin E2. Mechanistically, uses molecular
CC oxygen inserting one oxygen atom into a substrate, and reducing the
CC second into a water molecule, with two electrons provided by NADPH via
CC cytochrome P450 reductase (CPR; NADPH-ferrihemoprotein reductase).
CC {ECO:0000269|PubMed:11370662}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=O2 + prostaglandin E2 + reduced [NADPH--hemoprotein reductase]
CC = 20-hydroxy prostaglandin E2 + H(+) + H2O + oxidized [NADPH--
CC hemoprotein reductase]; Xref=Rhea:RHEA:52488, Rhea:RHEA-COMP:11964,

CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=0.05 mM for prostaglandin E2 {ECO:0000269|PubMed:11370662};
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000305|PubMed:11370662}; Single-pass type I membrane protein
CC {ECO:0000255}. Microsome membrane {ECO:0000305|PubMed:11370662};
CC Single-pass type I membrane protein {ECO:0000255}.
CC -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
