Gothel, S.F. and Marahiel, M.A. (1999) Peptidyl-prolyl cis-trans isomerases, a superfamily of ubiquitous folding catalysts. Cellular and Molecular Life Sciences 55, 423-436. [Pg.196]

The p(25-35) interacts with the native protein, destroys its native conformation, and forms pathological aggregates. Its action is exactly opposite to that of a chaperone, which helps proteins fold correctly. Hence, p(25-35) is termed as an antichaperone, protein disulphide isomerase (PDI), a folding catalyst and chaperone, under certain conditions, can facilitate the... [Pg.2483]

Improperly Folded Proteins in the ER Induce Expression of Protein-Folding Catalysts... [Pg.678]

The accumulation of abnormally folded proteins and unassembled subunits in the ER can induce increased expression of ER protein-folding catalysts via the unfolded-proteln response (see Figure 16-22). [Pg.680]

The disulfide formation depends on the protein conformation that places Cys residues into appropriate proximity and the disulfide redox potential that determines the intrinsic stability of protein disulfide bonds. For catalytic activity, the reduced dithiol form of protein disulfide isomerase is required. Protein disulfide isomerase is a folding catalyst that assists protein folding (Gilbert, 1997). The enzyme increases the rate of the overall folding process of the substrate protein without altering its pathway. [Pg.487]
