Relative reactivation rates of OP inhibited hD134H; hD134H_E202Q and hD134H_F338A.

hAChE OP OXIME Relative Reactivation Rate
wt 1 Paraoxon 2PAM 1
D134H 6
D134H_E202Q 0.1
D134H_F338A 1
wt 2 HI6 1
D134H 3
wt 3 SP CHMPTCh 2PAM 1
D134H 2
wt 4 HI6 1
D134H 0.3
D134H_E202Q 0.02
D134H_F338A 0.002
wt 5 VX analogue 2PAM 1
D134H 1
wt 6 RP IPMPTCh 2PAM 1
D134H 1

The second order rate constants for reactivation of OP inhibited wt hAChE by oximes were:

1

120 M-1min-1 (paraoxon inhibited hAChE reactivated by 2PAM)

2

45 M-1min-1 (paraoxon inhibited wt hAChE reactivated by HI6)

3

275 M-1min-1 (SPCHMPTCh inhibited wt hAChE reactivated by 2PAM)

4

13000 M-1min-1(SPCHMPTCh inhibited wt hAChE reactivated by HI6)

5

490 M-1min-1(VX inhibited wt hAChE reactivated by 2PAM)

6

270 M-1min-1(RPIPMPTCh inhibited wt hAChE reactivated by 2PAM).

Reactivation of cyclosarin and soman inhibited hAChE was not measured.
