3.2.1.2 | 2,3-epoxypropyl-alpha-D-glucopyranoside |
affinity-labeling reagent, mode of binding, covalently bound to the catalytic residue Glu-172, inactivation mechanism |
|
3.2.1.2 | 2-mercaptoethanol |
4%, 1h, activity is decreased to 53% |
|
3.2.1.2 | 3,4-epoxybutyl-alpha-D-glucopyranoside |
affinity-labeling reagent, mode of binding, covalently bound to the catalytic residue Glu-172 |
|
3.2.1.2 | 4-chloromercuribenzoate |
inactivation, the enzyme can be reactivated by L-cysteine |
|
3.2.1.2 | 5,5'-dithiobis-(2-nitrobenzoic acid) |
chemical modification of the exposed sulfhydryl groups in beta-amylase from unmalted seeds with 5,5'-dithiobis-(2-nitrobenzoic acid) results in loss of activity. In the beta-amylase from malted seed the 5,5'-dithiobis-(2-nitrobenzoic acid) chemical modification results in the increase in the KM from 2.81 to 4.14 mg/ml |
