Catalytic mechanism of the metal-dependent fuculose aldolase from Escherichia coli as derived from the structure.
M.K.Dreyer, G.E.Schulz.
The structure of L-fuculose-1-phosphate aldolase in a cubic crystal form has been determined with and without the inhibitor phosphoglycolohydroxamate at 2.4 and 2.7 angstrom (1 angstrom = 0.1 nm) resolution, respectively. This inhibitor mimics the enediolate transition state of the substrate moiety dihydroxyacetone phosphate. The structures showed that dihydroxyacetone phosphate ligates the zinc ion of this metal-dependent class II aldolase with its hydroxyl and keto oxygen atoms, shifting Glu73 away from the zinc coordination sphere to a non-polar environment. At this position Glu73 accepts a proton in the initial reaction step, producing the enediolate which is then stabilized by the zinc ion. The other substrate moiety L-lactaldehyde was modeled, because no binding structure is yet available.

Figure 3. Stereo view of the active center of FucA with positive (green) and negative (red) difference density at 23.5s levels after soaking with PGH. Phases were taken from the unligated structure without sulfate, chloride and water. The depicted residues are 21 to 31, 40 to 46 and 70 to 162 (black). Residues of the neighboring subunit are 109' to 123', 159' to 174' and 198' to 206' (blue). The fitted PGH model is given in gold. The side-chains of Ala27, Asn29, Thr43, Ser71, Ser72, Glu73 (still in the Zn 2+ coordination sphere), Phe131, Tyr113' and Phe206' are introduced.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
