P78061 Gamma-glutamylputrescine synthetase PuuA; Gamma-Glu-Put synthetase; Glutamate--putrescine ligase; EC 6.3.1.11 from Escherichia coli (strain K12) (see paper)

- H282 (= H257) mutation to N: Activity is impaired to 9% of wild-type.
- R357 (= R333) mutation to Q: Activity is impaired to 3% of wild-type.
P12425 Glutamine synthetase; GS; Glutamate--ammonia ligase; Glutamine synthetase I alpha; GSI alpha; EC 6.3.1.2 from Bacillus subtilis (strain 168) (see 5 papers)
31% identity, 90% coverage: 47:447/448 of query aligns to 41:443/444 of P12425
- G59 (≠ R65) 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 (≠ G68) 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 (= E136) binding
- E134 (= E138) binding
- E189 (= E201) binding
- V190 (≠ M202) 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 (= E208) binding
- G241 (= G253) binding
- H245 (= H257) binding
- G302 (≠ P314) 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 (≠ A316) 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 (= P318) 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 (= E345) binding
- E424 (= E428) 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.
