- G59 (= G87) mutation to R: Unable to form stable complex with TnrA. In the presence of glutamine, this mutant derepresses amtB-lacZ fusion and glnRA-lacZ fusion.
- R62 (≠ M90) Important for inhibition by glutamine; mutation to 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.
- E132 (= E159) binding
- E134 (= E161) binding
- E189 (= E226) binding
- V190 (= V227) 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 (= E235) binding
- G241 (≠ S281) binding
- H245 (= H285) binding
- G302 (≠ Y344) 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 (≠ N346) 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 (= P348) 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 (= E376) binding
- E424 (= E458) 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.
