LACTALDEHYDE:1,2-PROPANEDIOL OXIDOREDUCTASE OF ESCHERICHIA COLI
Overview
The FucO protein, a member of the group III "iron-activated", dehydrogenases, catalyzes the interconversion between L-lactaldehyde and, L-1,2-propanediol in Escherichia coli. The three-dimensional structure of, FucO in a complex with NAD(+) was solved, and the presence of iron in the, crystals was confirmed by X-ray fluorescence. The FucO structure presented, here is the first structure for a member of the group III bacterial, dehydrogenases shown experimentally to contain iron. FucO forms a dimer, in which each monomer folds into an alpha/beta dinucleotide-binding, N-terminal domain and an all-alpha-helix C-terminal domain that are, separated by a deep cleft. The dimer is formed by the swapping (between, monomers) of the first chain of the beta-sheet. The binding site for, Fe(2+) is ... [(full description)]
