E45 (= E54) mutation to N: 50-fold decrease in catalytic efficiency and 6-fold decrease of binding affinity.
R49 (≠ N58) binding
T73 (= T83) binding
K133 (= K143) binding covalent; mutation to Q: Absence of aldolase activity. Shows a markedly altered substrate specificity relative to the wild-type, with an enhanced activity against pyridine carboxaldehyde, benzaldehyde, and alpha-ketobutyrate; when associated with k-161.
T161 (≠ V171) binding ; mutation to K: Shows activity significantly greater than wild-type. Shows a markedly altered substrate specificity relative to the wild-type, with an enhanced activity against pyridine carboxaldehyde, benzaldehyde, and alpha-ketobutyrate; when associated with Q-133.; mutation to V: Little stereoselectivity, accepting KDPG and KDPGal as substrate with roughly equal efficacy. It strongly diminishes the activity against KDPG and slightly increases activity against KDPGal.
