Disease relevance of gldA

• Cloning and characterization of a gene from Bacillus stearothermophilus var. non-diastaticus encoding a glycerol dehydrogenase [1].
• Recombinant E. coli harboring the P450cam system, but lacking GLD, exhibited little activity for camphor hydroxylation [2].

High impact information on gldA

• In contrast, coexpression of GLD with the proteinaceous electron transfer components of P450cam resulted in about tenfold improvement in the substrate conversion, implying that the whole cell biocatalyst utilized molecular oxygen, endogenous NADH, and glycerol in the cell for catalysis [2].
• We purified and characterized glycerol dehydrogenase from Hansenula ofunaensis and prepared optically active 1,2-octanediol using a recombinant Escherichia coli harboring the glycerol dehydrogenase gene [3].

Associations of gldA with chemical compounds

• The addition of glycerol to the reaction media further promoted camphor hydroxylation, suggesting that exogenous glycerol is also available for GLD in the host cell and actively participates in the catalytic cycle [2].
• Our glycerol dehydrogenase catalyzed the NAD(+)-dependent oxidation of long-chain secondary alcohols such as 1,2-pentanediol, 1,2-hexanediol, 1,2-heptanediol, and 1,2-octanediol [3].
