Also known as OPLA5-Opase
Summary
OPLAH (5-oxoprolinase, ATP-hydrolysing, HGNC:8149) is a protein-coding gene on chromosome 8q24.3, encoding 5-oxoprolinase (O14841). Catalyzes the cleavage of 5-oxo-L-proline to form L-glutamate coupled to the hydrolysis of ATP to ADP and inorganic phosphate.
The protein encoded by this gene acts as a homodimer, using ATP hydrolysis to catalyze the conversion of 5-oxo-L-proline to L-glutamate. Defects in this gene are a cause of 5-oxoprolinase deficiency (OPLAHD).

Literature-anchored findings (GeneRIF, showing 3)
- the cause of cellular ATP depletion in nephrotic cystinosis may be the futile cycle, formed between two ATP-dependant gamma-glutamyl cycle enzymes, gamma-glutamyl cysteine synthetase and 5-oxoprolinase (PMID:20413906)
- In this study, clinical, biochemical, and genetic aspects of five Chinese 5-oxoprolinuria patients with OPLAH or GSS gene mutations were investigated. (PMID:25851806)
- An autosomal recessive mode of inheritance for 5-oxoprolinase deficiency is further supported by the identification of a single mutation in all 9/14 parent sample sets investigated (except for the father of one patient whose result suggests homozygosity), and the absence of 5-oxoprolinuria in all tested heterozygotes (PMID:27477828)
