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.
Most amino acids are synthesized from α-ketoacids, and later transaminated from another amino acid, usually glutamate. The enzyme involved in this reaction is an aminotransferase. α-ketoacid + glutamate ⇄ amino acid + α-ketoglutarate. Glutamate itself is formed by amination of α-ketoglutarate: α-ketoglutarate + NH + 4 ⇄ glutamate
MyPlate is the latest nutrition guide from the USDA. The USDA's first dietary guidelines were published in 1894 by Wilbur Olin Atwater as a farmers' bulletin. [4] Since then, the USDA has provided a variety of nutrition guides for the public, including the Basic 7 (1943–1956), the Basic Four (1956–1992), the Food Guide Pyramid (1992–2005), and MyPyramid (2005–2013).

6-Diazo-5-oxo-L-norleucine (DON) is a glutamine antagonist, which was isolated originally from Streptomyces in a sample of Peruvian soil. This diazo compound is biosynthesized from lysine by three enzymes in bacteria. [ 2 ]
