| - | The molecular architecture of the Class II E. coli fructose 1,6-bisphosphate aldolase dimer was determined to 1.6 A resolution. The subunit fold corresponds to a singly wound alpha/beta-barrel with an active site located on the beta-barrel carboxyl side of each subunit. In each subunit there are two mutually exclusive zinc metal ion binding sites, 3.2 A apart; the exclusivity is mediated by a conformational transition involving side-chain rotations by chelating histidine residues. A binding site for K+ and NH4+ activators was found near the beta-barrel centre. Although Class I and Class II aldolases catalyse identical reactions, their active sites do not share common amino acid residues, are structurally dissimilar, and from sequence comparisons appear to be evolutionary distinct. | ||
