methylglyoxal reductase (NADPH) (acetol producing) activity
Definition
Target type: molecularfunction
Catalysis of the reaction: hydroxyacetone + NADP+ = H+ + methylglyoxal + NADPH. [PMID:16077126, RHEA:27986]
Methylglyoxal reductase (NADPH) (acetol producing) activity catalyzes the reduction of methylglyoxal, a toxic by-product of glycolysis, to acetol using NADPH as a reducing agent. This reaction is crucial for detoxification and cellular protection, as methylglyoxal can damage proteins, DNA, and other cellular components. The enzyme plays a significant role in maintaining cellular redox balance and preventing oxidative stress. The mechanism involves the binding of methylglyoxal and NADPH to the enzyme active site, followed by a series of electron transfers that ultimately reduce methylglyoxal to acetol. The active site typically contains a cysteine residue that participates in the catalytic reaction. Methylglyoxal reductase (NADPH) (acetol producing) activity is highly conserved across various organisms, indicating its fundamental importance in cellular metabolism and survival.'
