Proprietà fisiche

Protein Disulfide Isomerase (PDI) from bovine liver is a homodimer with a molecular weight of 107 kDa (gel filtration) and the molecular weight of the monomer has been reported at 57 kDA (SDS-PAGE). The enzyme is a glycoprotein with 12% total carbohydrate content, composed of 4.6% mannose, 2.5% galactose, 1.4% NANA, and 3.5% 2-acetamido-2-deoxyglucose.

Definizione di unità

1 unit corresponds to the amount of enzyme, which, in a glutathione-dithiothreitol-system, causes a change of absorbance of 0.001 per minute at pH 4.0 and 25°C.

Enzyme-mediated disulfide bond formation is a highly conserved process affecting over one-third of all eukaryotic proteins. The enzymes primarily responsible for facilitating thiol-disulfide exchange are members of an expanding family of proteins known as protein disulfide isomerases (PDIs). These proteins
