Formaldehyde dehydrogenase from bakers' yeast.
نویسندگان
چکیده
In the course of studies of formaldehyde metabolism in yeast (I), an enzyme was found that catalyzed the oxidation of formaldehyde in the presence of glutathione and diphosphopyridine nucleotide. A similar enzyme was discovered independently by Strittmatter and Ball in liver (2). This paper describes the partial purification and some of the properties of yeast formaldehyde dehydrogenase. Some evidence bearing on the role of glutathione in the reaction is given.

Bioconversion of airborne formaldehyde by immobilized formaldehyde dehydrogenase from the recombinant methylotrophic yeast Hansenula polymorpha
Formaldehyde (FA) is a very toxic pollutant. FA in indoor air has a negative effect on human health and should be removed by ventilation or by conversion to non-toxic products. The formaldehyde dehydrogenase (FdDH), a NADand glutathione-dependent enzyme from recombinant methylotrophic yeast Hansenula polymorpha, was tested for its ability to oxidize airborne FA. A continuous fluidized bed biore...
متن کاملReduction of Acyl Enolates of a-Substituted /?-Keto Esters by Bakers' Yeast
Enol esters of 2-substituted-3-oxoalkanoates of (Z)-configuration were reduced by bakers' yeast to chiral 2-substituted-3-hydroxyalkanoates. The sy/f-selectivities of this reaction increased compared with those of the reduction of the corresponding racemic keto esters. The reaction mayproceed via an asymmetric hydrolysis of the enol esters, followed by the reduction of the resulting carbonyl gr...
متن کاملSubstrate specificity and stereospecificity of nicotinamide adenine dinucleotide-linked alcohol dehydrogenases from methanol-grown yeasts.
Nicotine adenine dinucleotide-linked primary alcohol dehydrogenase and a newly discovered secondary alcohol dehydrogenase coexist in most strains of methanol-grown yeasts. Alcohol dehydrogenases from methanol-grown yeasts oxidize (--)-2-butanol preferentially over its (+) enantiomorph. This is substantially different from alcohol dehydrogenases from bakers' yeast and horse liver.
متن کاملInduction of D(-)- and L-lactic cytochrome c reductase in yeast.
Aerobically grown bakers’ yeast has been shown to contain two different lactic cytochrome c reductases, one of which is specific for L( +)-lactate (1) and the other of which is specific for D( -)-lactate (2). Neither of these two enzymes is present in anaerobically grown yeast, which contains instead a D( -)lactic dehydrogenase that does not reduce cytochrome c. No L( +)-lactic dehydrogenase is...
متن کاملMolecular characterization of the Hansenula polymorpha FLD1 gene encoding formaldehyde dehydrogenase.
Glutathione-dependent formaldehyde dehydrogenase (FLD) is a key enzyme required forthe catabolism of methanol as a carbon source and certain primary amines, such as methylamine as nitrogen sources in methylotrophic yeasts. Here we describe the molecular characterization of the FLD1 gene from the yeast Hansenula polymorpha. Unlike the recently described Pichia pastoris homologue, the H. polymorp...
