3.4.21.83
C256S
750fold reduction in inhibition rate constant for iodoacetic acid and more than 100fold reduction in inhibition rate constant for NEM compared to wild-type enzyme

3.4.21.83
C544A
the enzymatic activity of the Cys-free mutant is markedly activated by the general thiol-reacting reagent dithiothreitol, oxidized glutathione, and reduced glutathione,the mutant is insensitive to the treatment of the SH-blocking reagent N-ethylmaleimide or H2O2

C559S
mutant shows significant decrease in activation by reducing agents. This residue may thus mediate the activity enhancing effect of reducing agents
