Then, more polymer layers are added and then cross-linked by disulfide bridges into a gel by means of a specially developed, very gentle cross-linking reaction.
Both a-lactalbumin and b-lactoglobulin can be extensively polymerized by transglutaminase when they are partly unfolded by the chemical reduction of the disulfide bridges stabilizing their tertiary structure, or by performing the reaction at alkaline pH.
Mechanisms by which SPINK1 could exert alternative functions were suggested by its structural similarities with epidermal growth factor (EGF): a 50% sequence homology, a molecular size of approximately 6 kDa, and the presence of 3 intrachain disulfide bridges (2).
Brazzein's rigidity originates from four links called disulfide bridges that lock in the protein's three-dimensional shape.
The UV light is absorbed by the amino acid tryptophan, which breaks the disulfide bridges holding parts of the antibody together and causes a particular part of the amino acid cysteine, called a thiol group, to become exposed at the tail end of the antibody.

Disulfide bridges play a major role in stabilization, the folding process and so, existence of cysteine residues and disulfide bonding pattern were determined using DISULFIND server (9).
Purpose; Due to an antioxidant substrate, high proportions of reducible disulfide bridges are typically for the viscotoxin 1-PS from Scots Pine (Pinus silvestris L.
