L-FUCULOSE-1-PHOSPHATE ALDOLASE COMPLEX WITH PGH
Overview
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 ... [(full description)]
