E132 (= E141) binding Mg(2+)
E134 (= E143) binding Mg(2+)
E189 (= E204) binding Mg(2+)
V190 (≠ A205) mutation to A: Unable to form stable complex with TnrA. In the presence of glutamine, this mutant partially relieves expression of the glnRA-lacZ fusion, but has no effect on the TnrA-dependent regulation of amtB-lacZ fusion. Resistant to inhibition by MetSox.
E196 (= E211) binding Mg(2+)
G241 (= G256) binding L-glutamate
H245 (= H260) binding Mg(2+)
G302 (= G319) mutation to E: Unable to form stable complex with TnrA. In the presence of glutamine, amtB-lacZ fusion is only 4-fold regulated by TnrA, whereas glnRA-lacZ fusion is derepressed. This mutant retains enzymatic specific activity with a 2-fold decrease of the affinity for glutamate and glutamine compared to the wild-type. Slightly less sensitive to inhibition by glutamine.
E304 (≠ F321) mutation to A: Highly resistant to Met-Sox inhibition. 8- and 2-fold increase of the affinity for glutamate and ATP, respectively. Strong decrease of the affinity for ammonium.
P306 (= P323) mutation to H: Unable to form stable complex with TnrA. In the presence of glutamine, this mutant completely derepresses glnRA-lacZ fusion, whereas amtB-lacZ fusion expression is only partially derepresses.
E333 (= E350) binding Mg(2+)
E424 (= E434) mutation to K: Unable to form stable complex with TnrA. In the presence of glutamine, this mutant derepresses amtB-lacZ fusion and glnRA-lacZ fusion. Although it is defective in regulation, this mutant retains enzymatic specific activity and similar affinity for ATP, glutamate and glutamine compared to the wild-type. Slightly less sensitive to inhibition by glutamine.

Sites not aligning to the query:

1 modified: Initiator methionine, Removed
59 G→R: Unable to form stable complex with TnrA. In the presence of glutamine, this mutant derepresses amtB-lacZ fusion and glnRA-lacZ fusion.
62 Important for inhibition by glutamine; R→A: Highly resistant to inhibition by glutamine and AMP. Regulation by TnrA and GlnR is abolished. Only small differences (less than 2-fold) in its steady-state kinetic constants compared with the wild-type. Similar sensitivity to Met-Sox that compared to the wild-ytpe.
