Protein Details
1. NADPH-dependent methylglyoxal reductase GRE2
General function:
Involved in catalytic activity
Specific function:
Catalyzes the irreversible reduction of the cytotoxic compound methylglyoxal (MG) to (R)-lactaldehyde as an alternative to detoxification of MG by glyoxalase I GLO1. MG is synthesized via a bypath of glycolysis from dihydroxyacetone phosphate and is believed to play a role in cell cycle regulation and stress adaptation
Gene Name:
GRE2
Uniprot ID:
Q12068
Molecular weight:
38169.19922
Reactions
Lactaldehyde + NADP(+) → methylglyoxal + NADPH.
3-methylbutanol + NAD(P)+ → 3-methylbutanal + NAD(P)H + H+
Protein Details
2. NADPH-dependent aldose reductase GRE3
General function:
Involved in oxidoreductase activity
Specific function:
Reduces the cytotoxic compound methylglyoxal (MG) to (R)-lactaldehyde similar to GRE2. MG is synthesized via a bypath of glycolysis from dihydroxyacetone phosphate and is believed to play a role in cell cycle regulation and stress adaptation. In pentose-fermenting yeasts, aldose reductase catalyzes the reduction of xylose into xylitol. The purified enzyme catalyzes this reaction, but the inability of S.cerevisiae to grow on xylose as sole carbon source indicates that the physiological function is more likely methylglyoxal reduction
Gene Name:
GRE3
Uniprot ID:
P38715
Molecular weight:

Reactions
Alditol + NAD(P)(+) → aldose + NAD(P)H.
(R)-lactaldehyde + NADP(+) → methylglyoxal + NADPH.
