Protein disulphide-isomerase of chick-embryo tendon.
Protein disulphide-isomerase can be partially purified from the high-speed-supernatant fraction of extensively disrupted chick-embryo tendon tissue. The catalytic properties of the preparation resemble those of the enzyme from mammalian liver. Gel electrophoresis and isoelectric focusing show the enzyme to be very acidic, with pI 4.4 +/- 0.3. Gel filtration indicates an Mr for the active enzyme...
متن کاملProtein disulphide isomerase
What is it? Protein disulphide isomerase is an enzyme with two interrelated activities: as an oxidoreductase, it can catalyse the formation, reduction and isomerisation of disulphide bonds; and as a polypeptide binding protein, it can function as a molecular chaperone which assists the folding of polypeptides. Transient association of PDI with nascent polypeptides during their folding prevents ...
متن کاملProtein disulphide-isomerase and the formation of native disulphide bonds.
Disulphide bonds are found in practically every class of extracellular protein, and the formation of disulphide bonds must be regarded as a key post-translational modification of secretory proteins. Despite this, and despite the fact that the existence of disulphide bonds has been known for many years, the mechanism of disulphide bond formation during protein biosynthesis and secretion is not w...
متن کاملDistribution of protein disulphide isomerase in rat liver mitochondria.
Here we report the localization of protein disulphide isomerase (PDI) in the mitochondrial compartments, comparing it with that of thioredoxin reductase. The latter enzyme is present mostly in the matrix, whereas PDI is located at the level of the outer membrane. We characterize the different submitochondrial fractions with specific marker enzymes. PDI, whether isolated from whole mitochondria ...
متن کاملSecretion of protein disulphide isomerase AGR2 confers tumorigenic properties
The extracellular matrix (ECM) plays an instrumental role in determining the spatial orientation of epithelial polarity and the formation of lumens in glandular tissues during morphogenesis. Here, we show that the Endoplasmic Reticulum (ER)-resident protein anterior gradient-2 (AGR2), a soluble protein-disulfide isomerase involved in ER protein folding and quality control, is secreted and inter...
