  Domain Name: LPO
Lactadehyde:propanediol oxidoreductase (LPO) catalyzes the interconversion between L-lactaldehyde and L-1,2-propanediol in Escherichia coli and other enterobacteria. Lactadehyde:propanediol oxidoreductase (LPO) is a member of the group III iron-activated dehydrogenases which catalyze the interconversion between L-lactaldehyde and L-1,2-propanediol in Escherichia coli and other enterobacteria. L-Fucose and L-rhamnose is used by Escherichia coli through an inducible pathway mediated by the fucose regulon comprising four linked oeprons fucO, fucA, fucPIK, and fucR. The fucA-encoded aldolase catalyzes the formation of dihydroxyacetone phosphate and L-lactaldehyde. Under anaerobic conditions, with NADH as a cofactor, lactaldehyde is converted by a fucO-encoded Lactadehyde:propanediol oxidoreductase (LPO) to L-1,2-propanediol, which is excreted as a fermentation product. In mutant strains, E. coli adapted to grow on L-1,2-propanediol, FucO catalyzes the oxidation of the polyol to L-lactaldehyde. FucO is induced regardless of the respiratory conditions of the culture, remains fully active in the absence of oxygen. In the presence of oxygen, this enzyme becomes oxidatively inactivated by a metal-catalyzed oxidation mechanism. FucO is an iron-dependent metalloenzyme that is inactivated by other metals, such as zinc, copper, or cadmium. This enzyme can also reduces glycol aldehyde with similar efficiency. Beside L-1,2-propanediol, the enzyme is also able to oxidize methanol as alternative substrates.
