IUBMB Enzyme Nomenclature


Accepted name: 2-methyl-1,2-propanediol dehydrogenase

Reaction: 2-methylpropane-1,2-diol + NAD+ = 2-hydroxy-2-methylpropanal + NADH + H+

Other name(s): mpdB (gene name)

Systematic name: 2-methylpropane-1,2-diol:NAD+ 1-oxidoreductase

Comments: This bacterial enzyme is involved in the degradation pathways of the alkene 2-methylpropene and the fuel oxygenate methyl tert-butyl ether (MTBE), a widely occurring groundwater contaminant.
