Pyrroline-5-carboxylate reductase 1 (PYCR1) catalyzes the reaction of (S)-1-pyrroline-5-carboxylate with NADH + H+ to form proline and NAD+ (De Ingeniis et al. 2012). The active enzyme is a homodecamer (Meng et al. 2006). Subcellular fractionation (De Ingeniis et al. 2012) and co-localization studies (Reversade et al. 2009) indicate that PYCR1 is mitochondrial. Its deficiency is associated with cutis laxa (Reversade et al. 2009).
