Common Name(2s,4r)-2-amino-4-hydroxypentanedioic acid
Description4-Hydroxy-L-glutamic acid, also known as 4-hydroxy-L-glutamate or L-erythro-4-hydroxyglutamate, belongs to the class of organic compounds known as glutamic acid and derivatives. Glutamic acid and derivatives are compounds containing glutamic acid or a derivative thereof resulting from reaction of glutamic acid at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Specifically, 4-hydroxy-L-glutamic acid combines with 2-oxoglutarate to produce 4-hydroxy-2-oxoglutarate and glutamate. 4-Hydroxy-L-glutamic acid is a very strong basic compound (based on its pKa). Within humans, 4-hydroxy-L-glutamic acid participates in a number of enzymatic reactions. In particular, 4-hydroxy-L-glutamic acid can be biosynthesized from pyrroline hydroxycarboxylic acid through its interaction with the enzyme Delta-1-pyrroline-5-carboxylate dehydrogenase, mitochondrial. In addition, 4-hydroxy-L-glutamic acid can be converted into L-4-hydroxyglutamate semialdehyde through its interaction with the enzyme proline dehydrogenase 1, mitochondrial. In humans, 4-hydroxy-L-glutamic acid is involved in the metabolic disorder called the arginine: Glycine amidinotransferase deficiency (agat deficiency) pathway. 4-Hydroxy-L-glutamic acid is an intermediate in the metabolism of gamma-hydroxyglutamic acid. This reaction is catalyzed by 4-Hydroxy-L-glutamic acid aminotransferase (PMID: 13948827 ). (2s,4r)-2-amino-4-hydroxypentanedioic acid is found in Linaria vulgaris. (2s,4r)-2-amino-4-hydroxypentanedioic acid was first documented in 1962 (PMID: 13948827). The reaction can be described as: 4-Hydroxy-L-glutamate + 2-oxoglutarate <=> 4-hydroxy-2-oxoglutarate + L-glutamate.
