ENOPH1 (Enolase-Phosphatase 1), also known as MST1. is a bifunctional enzyme encoded by the ENOPH1 gene in humans. It plays a critical role in the methionine salvage pathway, a conserved metabolic route that regenerates methionine from methylthioadenosine (MTA), a byproduct of polyamine biosynthesis. The enzyme sequentially catalyzes two reactions: the dehydration of 2.3-diketo-5-methylthiopentyl-1-phosphate (DK-MTP-1-P) to enol-form intermediates, followed by phosphate hydrolysis to produce acireductone. This pathway is essential for maintaining sulfur metabolism, redox balance, and polyamine homeostasis in cells.
Structurally, ENOPH1 belongs to the cupin superfamily, characterized by a conserved β-barrel fold. Its dual enzymatic activity is facilitated by distinct active sites within a single protein scaffold. Dysregulation of ENOPH1 has been implicated in various diseases, including cancer, neurological disorders, and inflammatory conditions. For instance, altered expression levels correlate with tumor progression in certain cancers, potentially linked to its role in modulating oxidative stress and apoptosis. In neuroscience, ENOPH1 variants have been associated with developmental delays and intellectual disabilities, though mechanistic insights remain under investigation.
Recombinant ENOPH1 proteins are typically produced in bacterial (e.g., E. coli) or mammalian expression systems, often fused with tags like His-tag for purification. These engineered proteins enable functional studies, structural analysis (e.g., X-ray crystallography), and high-throughput screening for therapeutic agents targeting the methionine salvage pathway. Their applications extend to elucidating enzyme kinetics, substrate specificity, and interactions with regulatory molecules. As research continues, ENOPH1 recombinant tools are proving vital for deciphering its pathophysiological roles and exploring potential diagnostic or therapeutic avenues.
