R16 (= R13) mutation R->K,Q: Loss of activity.
RD 16:17 (= RD 13:14) binding pyruvate
D17 (= D14) mutation to A: 34-fold increase in Km for pyruvate and 315-fold decrease in kcat.; mutation to N: 4.4-fold increase in Km for pyruvate and 480-fold decrease in kcat.
L81 (≠ A71) mutation to A: 4.7-fold increase in Km for pyruvate and 15.7-fold decrease in kcat.; mutation to V: 3.3-fold increase in Km for pyruvate and 10.1-fold decrease in kcat.
F83 (≠ L73) mutation to A: 5-fold increase in Km for acetyl-CoA and 120-fold decrease in kcat.
L104 (≠ F99) mutation to V: 1.8-fold increase in Km for pyruvate and 3.4-fold decrease in kcat.
Y144 (≠ S139) binding pyruvate; mutation to L: 259-fold increase in Km for pyruvate and 76-fold decrease in kcat.; mutation to V: 114-fold increase in Km for pyruvate and 5.3-fold decrease in kcat.
E146 (≠ M141) mutation E->D,Q: Minor effects on the binding of acetyl-CoA, but causes a strong decrease in kcat.
T179 (= T171) binding pyruvate; mutation to A: 16.4-fold increase in Km for pyruvate and 186-fold decrease in kcat.
H302 (= H300) mutation H->A,N: Loss of activity.
D304 (= D302) mutation to A: 5.2-fold increase in Km for acetyl-CoA and 16.6-fold decrease in kcat.
N310 (≠ A308) mutation to A: 2.2-fold increase in Km for acetyl-CoA and 1.7-fold decrease in kcat.
L311 (≠ S309) mutation to A: 8-fold increase in Km for acetyl-CoA and 6-fold decrease in kcat.
Y312 (≠ T310) mutation to A: Loss of activity.
Y430 (≠ I430) mutation to L: No change in Km for acetyl-CoA and 2.3-fold decrease in kcat. Severely impairs inhibition by isoleucine.
D431 (= D431) mutation to A: 1.8-fold decrease in Km for acetyl-CoA and 5-fold decrease in kcat.
L451 (= L447) mutation to V: 1.5-fold increase in Km for acetyl-CoA and 4.3 decrease in kcat.
Y454 (≠ F450) mutation to A: 1.4 decrease in Km for acetyl-CoA and 17-fold decrease in kcat. Still inhibited by isoleucine and weakly inhibited by leucine.
I458 (≠ S454) mutation to A: 1.3-fold decrease in Km for acetyl-CoA and 14-fold decrease in kcat. Abolishes inhibition by isoleucine.
T464 (= T459) mutation to A: 1.8-fold decrease in Km for acetyl-CoA and 4.3-fold decrease in kcat.
V468 (≠ G463) mutation to A: No change in Km for acetyl-CoA and 2-fold decrease in kcat. Increases inhibition by isoleucine and leucine becomes an effective inhibitor.
P493 (= P483) mutation to A: 1.5-fold decrease in Km for acetyl-CoA and 2.6-fold decrease in kcat.
Q495 (≠ I485) mutation to A: 1.6-fold decrease in Km for acetyl-CoA and 2.8-fold decrease in kcat.

H103 (≠ L73) binding 2-oxoglutarate; mutation to A: Substantially impairs catalytic efficiency.
D123 (≠ H97) binding L-lysine; mutation to N: Does not affect the catalytic activity but impairs L-lysine inhibition.
R163 (≠ E137) binding 2-oxoglutarate; mutation R->A,Q: Abolishes the catalytic activity.; mutation to K: Severely diminishes affinity for 2-oxoglutarate and substantially impairs catalytic efficiency.
S165 (= S139) binding 2-oxoglutarate; mutation to A: Results in a moderate decrease in catalytic efficiency.
E167 (≠ M141) mutation E->A,Q: Abolishes the catalytic activity.
T197 (= T171) binding 2-oxoglutarate; binding L-lysine; mutation to A: Exhibits a 25-fold decrease in catalytic efficiency.; mutation to S: Results in a modest decrease in catalytic efficiency.; mutation to V: Abolishes the catalytic activity.
E222 (≠ S200) mutation to Q: Does not affect the catalytic activity but impairs L-lysine inhibition.
H224 (= H202) binding 2-oxoglutarate; binding Zn(2+)
H226 (= H204) binding 2-oxoglutarate; binding Zn(2+)
R288 (≠ Y267) mutation to K: Does not affect the catalytic activity but impairs L-lysine inhibition.
Y332 (≠ F311) mutation to A: Abolishes the catalytic activity.; mutation to F: Results in a decrease in catalytic efficiency.
Q364 (≠ V343) mutation to R: Does not affect the catalytic activity but impairs L-lysine inhibition.
