RABBIT MUSCLE ALDOLASE A/FRUCTOSE-1,6-BISPHOSPHATE COMPLEX
Overview
Class I fructose-1,6-bis(phosphate) aldolase is a glycolytic enzyme that, catalyzes the cleavage of fructose 1,6-bis(phosphate) through a covalent, Schiff base intermediate. Although the atomic structure of this enzyme is, known, assigning catalytic roles to the various enzymic active-site, residues has been hampered by the lack of a structure for the, enzyme-substrate complex. A mutant aldolase, K146A, is unable to cleave, the C3-C4 bond of the hexose while retaining the ability to form the, covalent intermediate, although at a greatly diminished rate. The, structure of rabbit muscle K146A-aldolase A, in complex with its native, substrate, fructose 1,6-bis(phosphate), is determined to 2.3 A resolution, by molecular replacement. The density at the hexose binding site differs, between ... [(full description)]
