Serendipitous Discovery of an Allosteric Inhibitor Binding Groove in the Proline Biosynthetic Enzyme Pyrroline-5-Carboxylate Reductase 1 (PYCR1)
{{output}}
Δ1-pyrroline-5-carboxylate (P5C) reductase 1 (PYCR1) catalyzes the NAD(P)H-dependent conversion of L-P5C to L-proline and is one of the most consistently upregulated metabolic enzymes in cancer cells. High PYCR1 expression is associated with adverse clinical ... ...
