proline oxidase (proline dehydrogenase, PRODH)

Function: - converts proline to delta-1-pyrroline-5-carboxylate - amino-acid degradation; L-proline degradation into L-glutamate; L-glutamate from L-proline: step 1/2 L-proline + acceptor + H2O (S)-1-pyrroline-5-carboxylate + reduced acceptor Cofactor: FAD Structure: belongs to the proline oxidase family Compartment: mitochondria matrix Alternative splicing: named isoforms=5 Expression: - expressed in lung, skeletal muscle & brain - lesser amounts in heart & kidney, & weakly in liver, placenta & pancreas - expressed during TP53-induced apoptosis Polymorphism: - variant in position: 8:P->L - variant in position: 19:Q->P (moderate reduction of enzymatic activity, dbSNP:rs2008720) - variant in position: 30:P->S - variant in position: 58:A->T Pathology: - defects in PRODH are the cause of hyperprolinemia type 1 - defects in PRODH may be associated with susceptibility to schizophrenia 4
