Haemophilus disulfide bonds cysteine
WebThe repeated groups of cysteine residues and disulfide bridges are commonly present in extracellular domains of membrane-bound receptors. Many extracellular or secreted proteins and peptides also have disulfide bridges, including some hormones, enzymes, plasma proteins, inhibitors, and venom proteins. WebIn proteins it usually exists as a cystine by forming a disulfide bond between two cysteine residues, carefully protected inside of the protein in order to function as a stabilizer for high-order structure of the protein, or an active center for its bioactivity.
