Activity summary

PYCR2 also known as Pyrroline-5-carboxylate reductase 2 is an enzyme involved in proline biosynthesis. It has a molecular mass of approximately 31 kDa. This protein catalyzes the conversion of pyrroline-5-carboxylate to proline an amino acid important for protein synthesis and cellular stress responses. Expressed broadly in human tissues PYCR2 shows notable expression in the liver brain and various muscle tissues indicating its wide functional relevance across different physiological systems.

Biological function summary

The enzyme participates in maintaining proline levels and contributes to cellular osmotic balance and protection against oxidative stress. It is not typically part of a larger protein complex but interacts with other metabolic enzymes that support similar stress response pathways. By catalyzing an important step in the proline biosynthesis pathway PYCR2 helps sustain cellular redox states and protein turnover rates under stressful conditions.

Pathways

PYCR2 plays a significant role in the proline metabolism pathway and glutamate pathway. The functioning of this enzyme in these pathways supports the synthesis and recycling of proline which is important for cell survival under osmotic and oxidative stress conditions. The enzyme cooperates indirectly with proteins such as glutamate dehydrogenase facilitating the metabolic flux through interconnected pathways that manage cellular nitrogen balance.

Associated diseases and disorders

Mutations in PYCR2 have been associated with conditions such as Hypomyelinating Leukodystrophy 10 and Proline Metabolism Disorder. These conditions often showcase symptoms related to central nervous system abnormalities and metabolic imbalances. The disruptions in PYCR2 activity may also alter interactions with proteins involved in these pathways such as Δ1-Pyrroline-5-carboxylate synthase thereby exacerbating the disease states.
