E45 (= E47) mutation to N: 50-fold decrease in catalytic efficiency and 6-fold decrease of binding affinity.
R49 (= R51) binding
T73 (= T75) binding
K133 (= K135) 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 (= T163) 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.
G163 (= G165) binding
N168 (≠ S170) mutation to S: Shows activity significantly greater than wild-type.
S184 (= S186) binding

T66 (= T75) binding
K126 (= K135) active site, Schiff-base intermediate with substrate; binding covalent
V154 (≠ T163) mutation to T: Little stereoselectivity, accepting KDPG and KDPGal as substrate with roughly equal efficacy. Reduced the preference for KDPGal. It diminishes the activity against KDPGal and increases activity against KDPG.
