Reaction: PRODH2:FAD dimer dehydrogenates HPRO to 1-pyrroline-3-hydroxy-5-carboxylate
- in pathway: Glyoxylate metabolism and glycine degradation
PRODH2 dimer dehydrogenates hydroxyproline (HPRO) to form 1-pyrroline-3-hydroxy-5-carboxylate (Adams & Goldstone 1960). The enzyme is associated with FAD and ubiquinone (not annotated here) is the likely electron acceptor (Summitt et al. 2015). The mitochondrial localization of the reaction is inferred from studies of HPRO catabolism in rat and bovine systems (Adams & Frank 1980), and the localization of PRODH2 to the inner mitochondrial membrane is inferred from that of the homologous mouse protein (Da Cruz et al. 2003).
