Metabolite Identification
Common NamePyrroline hydroxycarboxylic acid
DescriptionPyrroline hydroxycarboxylic acid is a metabolite identified in the urine of patients with type II hyperprolinemia. (OMIM 239510 ). The urinary excretion of Pyrroline hydroxycarboxylic acid increased in hyperprolinemic patients but not in healthy controls during oral loading of hydroxyproline and hydroxyproline-ornithine. (PMID: 533224 ). Hyperprolinemia type II (HP II) is a rare inherited metabolic disease due to the deficiency of pyroline-5-carboxylate dehydrogenase. It is generally believed to be a benign condition although some patients have neurological problems such as refractory convulsions. (PMID: 15214748 ). The oxidation of pyrroline-carboxylate generates glutamate and pyrroline-hydroxycarboxylate, a reaction catalyzed by hydroxyproline oxidase (PMID: 500817 ).

Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
Irreversible conversion of delta-1-pyrroline-5-carboxylate (P5C), derived either from proline or ornithine, to glutamate. This is a necessary step in the pathway interconnecting the urea and tricarboxylic acid cycles. The preferred substrate is glutamic gamma-semialdehyde, other substrates include succinic, glutaric and adipic semialdehydes.
