Inhibitors | Comment | Organism | Structure |
---|---|---|---|
iodoacetamide | 3.2 mM, 10% inhibition | Escherichia coli K-12 | |
iodoacetate | 15% protection against inhibition with 5 mM NAD+, 30% with 5 mM L-threonine, 60-70% protection in the presence of both NAD+ and L-threonine, inactivation occurs more rapidly in the presence of Cd2+; enzyme contains 6 half-cystine residues per subunit, 2 disulfide bonds and 4 sulfhydryl groups | Escherichia coli K-12 | |
methylmethanethiosulfonate | 0.4 mM, 350fold molar excess over enzyme sulfhydryl groups leads to complete inactivation | Escherichia coli K-12 | |
p-mercuribenzoate | 10fold excess leads to immidiate inactivation | Escherichia coli K-12 | |
thionitrobenzoate | 40fold molar excess, gradual 99% loss of enzyme activity | Escherichia coli K-12 |
