L-FUCULOSE-1-PHOSPHATE ALDOLASE FROM ESCHERICHIA COLI MUTANT Y113FL-FUCULOSE-1-PHOSPHATE ALDOLASE FROM ESCHERICHIA COLI MUTANT Y113F
Structural highlights
Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedPrevious analyses established the structures of unligated L-fuculose 1-phosphate aldolase and of the enzyme ligated with an inhibitor mimicking the substrate dihydroxyacetone phosphate. These data allowed us to suggest a catalytic mechanism. On the basis of this proposal, numerous mutations were now introduced at the active center and tested with respect to their catalytic rates and their product distributions. For several mutants, the structures were determined. The results demonstrate the catalytic importance of some particular residues in defined conformations and in the mobile C-terminal chain end. Moreover, they led to a modification of the proposed mechanism. The effect of some mutations on enantioselectivity and on the ratio of diastereomer formation indicates clearly the binding site of the aldehyde moiety in relation to the other substrate dihydroxyacetone phosphate. Catalytic action of fuculose 1-phosphate aldolase (class II) as derived from structure-directed mutagenesis.,Joerger AC, Gosse C, Fessner WD, Schulz GE Biochemistry. 2000 May 23;39(20):6033-41.
