DESCRIPTION

Also known as FUCA_ECOLI, fucA, fucC, prd. Involved in the degradation of L-fucose and D-arabinose (PubMed:13898172). Catalyzes the reversible cleavage of L-fuculose 1-phosphate (Fuc1P) to yield dihydroxyacetone phosphate (DHAP) and L-lactaldehyde (PubMed:13898172, Ref.8, Ref.9, PubMed:10821675, PubMed:11054289). Also able to catalyze the reversible cleavage of D-ribulose 1-phosphate, but FucA has a higher affinity for L-fuculose 1-phosphate and L-lactaldehyde than for D-ribulose 1-phosphate and glycolaldehyde, respectively (PubMed:4928018). FucA possesses a high specificity for the dihydroxyacetone phosphate (DHAP), but accepts a great variety of different aldehydes and has a strong preference for L-configurated alpha-hydroxy aldehydes (PubMed:13898172, Ref.8, PubMed:10821675). FucA generates a vicinal diol unit having the absolute (3R, 4R)-cis configuration (D-erythro) (Ref.8, PubMed:10821675). Homotetramer.
