In enzymology, a 5-oxoprolinase (ATP-hydrolysing) (EC 3.5.2.9) is an enzyme that catalyzes the chemical reaction. ATP + 5-oxo-L-proline + 2 H 2 O ADP + phosphate + L-glutamate. The 3 substrates of this enzyme are ATP, 5-oxo-L-proline, and H 2 O, whereas its 3 products are ADP, phosphate, and L-glutamate.
The names of pyroglutamic acid conjugate base, anion, salts, and esters are pyroglutamate, 5-oxoprolinate, or pidolate. Formation of pyroglutamic acid from N-terminal glutamine. It is a metabolite in the glutathione cycle that is converted to glutamate by 5-oxoprolinase. Pyroglutamate is found in many proteins including bacteriorhodopsin.
Mild glutathione synthetase deficiency usually results in the destruction of red blood cells (hemolytic anemia). Rarely, affected people also excrete large amounts of a compound called 5-oxoproline (also called pyroglutamic acid, or pyroglutamate) in their urine (5-oxoprolinuria). This compound builds up when glutathione is not processed ...
That means it can build up in the body, with Peaslee noting that perfluorohexanoic acid “bioaccumulates” in the blood. “One recent Swedish study reports it to be the third most abundant PFAS ...

The four amino acids bind to the site by their common atoms, “the main chain” of amino acids. [5] Glutamate is another product of glutamine metabolism; however, glutamate is a substrate for GS inhibiting it to act as a regulator to GS.2 Each inhibitor can reduce the activity of the enzyme; once all final glutamine metabolites are bound to ...
Breen’s suit claims Olson-Kennedy’s clinic put her on puberty blockers when she was just 12, started her on hormone therapy at 13 and performed a double mastectomy on her at 14.
Glutamate transporters are a family of neurotransmitter transporter proteins that move glutamate – the principal excitatory neurotransmitter – across a membrane.The family of glutamate transporters is composed of two primary subclasses: the excitatory amino acid transporter (EAAT) family and vesicular glutamate transporter (VGLUT) family.
