Pyrroline-5-carboxylate reductase 1, mitochondrial is anenzyme that in humans is encoded by thePYCR1gene.[5][6]

This gene encodes an enzyme that catalyzes the NAD(P)H-dependent conversion ofpyrroline-5-carboxylate toproline. This enzyme may also play a physiologic role in the generation of NADP(+) in some cell types. The protein forms a homopolymer and localizes to the mitochondrion. Alternate splicing results in two transcript variants encoding different isoforms.[6] As reported byBruno Reversade and colleagues, PYCR1 deficiency in humans causes aprogeroid disease known asDe Barsy Syndrome mainly affecting connective tissues withdermis thinning and bone fragility.[7]
