Has a preference for the D-aldehyde and shows an inversion of the diastereoselectivity. Loss of aldolase activity; when associated with Q-73 and F-209.
F131 (= F135) Plays a key role in the stabilization of the transition state and positioning the aldehyde component; mutation to A: Has a slight preference for the D-aldehyde and shows an inversion of the diastereoselectivity. Loss of aldolase activity; when associated with W-206.
H155 (= H159) binding
F206 (= F209) mutation to W: Decrease of aldolase activity mostly due to a decrease of the affinity for L-fuculose 1-phosphate (Fuc1P). Loss of aldolase activity; when associated with A-131.
Y209 (= Y212) Plays a key role in the stabilization of the transition state and positioning the aldehyde component; mutation to F: Slowly inactivated and unable to discriminate between the enantiomers. Shows an inversion of the diastereoselectivity. Loss of aldolase activity; when associated with Q-73 and F-113.

N28 (= N28) mutation to A: Strong decrease of the affinity for L-ribulose 5-phosphate (LRu5P).
K42 (≠ T44) mutation to M: Strong decrease of the affinity for L-ribulose 5-phosphate (LRu5P).
D76 (≠ E77) mutation to N: Mutant shows a strong decrease of the catalytic efficiency, but it retains considerable epimerase activity. The affinity for L-ribulose 5-phosphate (LRu5P) is relatively unaffected.
H95 (= H96) binding ; mutation to N: Mutant shows a strong decrease of the catalytic efficiency and a reduced affinity for Zn(2+).
H97 (= H98) binding ; mutation to N: Mutant shows a strong decrease of the catalytic efficiency and a reduced affinity for Zn(2+). Inhibited by glycolaldehyde phosphate.
T116 (≠ Y117) mutation T->E,Y: Loss of the epimerase activity due to an increased steric bulk introduced by the mutation which causes a conformational change that is incompatible with catalysis.
D120 (≠ R121) mutation to N: Loss of the epimerase activity.
E142 (≠ L140) mutation to Q: Mutant shows a strong decrease of the catalytic efficiency, but it retains considerable epimerase activity. The affinity for L-ribulose 5-phosphate (LRu5P) is relatively unaffected.
H171 (= H159) binding

Sites not aligning to the query:

218 H→N: Mutant shows a strong decrease of the catalytic efficiency, but it retains considerable epimerase activity. The affinity for L-ribulose 5-phosphate (LRu5P) is relatively unaffected.
