Definition of hydroxylase : any of a group of enzymes that catalyze oxidation reactions in which one of the two atoms of molecular oxygen is incorporated into the substrate and the other is used to oxidize NADH or NADPH.
Is hydroxylase a protein?
Protein hydroxylation is a post-translational modification catalyzed by 2-oxoglutarate-dependent dioxygenases. The hydroxylation modification can take place on various amino acids, including but not limited to proline, lysine, asparagine, aspartate and histidine.
Where does 17α hydroxyprogesterone come from during pregnancy?
17α-OHP increases in the third trimester of pregnancy primarily due to fetal adrenal production. This steroid is primarily produced in the adrenal glands and to some degree in the gonads, specifically the corpus luteum of the ovary.
Do you need to test for 17 hydroxyprogesterone?
By contrast, in 2 less common forms of CAH, due to 17-hydroxylase or 11-hydroxylase deficiency, OHPG and androstenedione levels are not significantly elevated and measurement of progesterone (PGSN / Progesterone, Serum) and deoxycorticosterone (FDOC / Deoxycorticosterone [DOC], Serum), respectively, are necessary for diagnosis.
When to use 17-ohpg as a pregnancy test?
Analysis for 17-OHPG is also useful as part of a battery of tests to evaluate females with hirsutism or infertility; both can result from adult-onset CAH Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
