P04805 Glutamate--tRNA ligase; Glutamyl-tRNA synthetase; GluRS; EC 6.1.1.17 from Escherichia coli (strain K12) (see 4 papers)
100% identity, 100% coverage: 1:471/471 of query aligns to 1:471/471 of P04805
- C98 (= C98) mutation to S: 10-fold decrease in activity. Strong decrease in zinc content.
- C100 (= C100) mutation to S: Loss of activity. Strong decrease in zinc content.; mutation to Y: Does not prevent zinc binding. Reduces only 2-fold the binding affinity for tRNA(Glu), but reduces more than 10-fold the affinity for glutamate in the presence of tRNA(Glu).
- C125 (= C125) mutation to S: Loss of activity. Strong decrease in zinc content.
- H127 (= H127) mutation to Q: 10-fold decrease in activity. Strong decrease in zinc content.
- H129 (= H129) mutation to Q: No change in activity or in zinc content.
- H131 (= H131) mutation to Q: No change in activity or in zinc content.
- H132 (= H132) mutation to Q: No change in activity or in zinc content.
- C138 (= C138) mutation to S: No change in activity or in zinc content.
- S239 (= S239) modified: Phosphoserine; mutation to D: Does not aminoacylate tRNA(Glu), not phosphorylated by HipA.
