Descrição geral
Donor: hydrogen-peroxide oxidoreductase
Peroxidase can be coupled to other proteins via its amino groups, as well as its carbohydrate moiety. The reconstituted solution can be used directly for conjugation without prior dialysis.

Aplicação
Peroxidase (POD) has been used in the spermine oxidase enzyme activity assay.[1]
Sequência
Blocking substances
Preparations does not contain substances that block the amino groups, but in contrast to other enzymes POD has only 2 to 3 free amino groups which are not accessible; even by extended dialysis of POD, the number of NH2-groups/mol does not change.
POD
POD contains 1 molecule of protoheme IX as prosthetic group and 2 molecules of Ca2+.
POD exists in > 10 isoenzymic forms (some sources estimate approx. 40 isoenzymes).
Carbohydrate Content
12 to 14.5 mg/100 mg Iyophilizate
Free Amino Groups
Free amino groups: 2 to 3 mol/mol enzyme
