• PubMed Abstract: 
  

  Staphylococcus aureus LacD, a Class I tagatose-1,6-bisphosphate (TBP) aldolase, shows broadened substrate specificity by catalyzing the cleavage of 1,6-bisphosphate derivatives of D-tagatose, D-fructose, D-sorbose, and D-psicose. LacD.1 and LacD.2 are two closely-related Class I TBP aldolases in Streptococcus pyogenes. Here we have determined the crystal structures of S. aureus LacD and S. pyogenes LacD.1. Monomers of both enzymes are folded into a (β/α)(8) barrel and two monomers associate tightly to form a dimer in the crystals. The structures suggest that the residues E189 and S300 of rabbit muscle Class I fructose-1,6-bisphosphate (FBP) aldolase are important for substrate specificity. When we mutated the corresponding residues of S. aureus LacD, the mutants (L165E, L275S, and L165E/L275S) showed enhanced substrate specificity toward FBP.
