Biochem/physiol Actions

Human insulin is made up of 51 amino acids. It consists of two peptide chains, 21 amino acids make up A-chain and chain B contains 31 amino acids. The two chains are linked together by a disulfide bond, to form a classical insulin fold with three α helices, chain A having two and one in chain B.
Insulin regulates the cellular uptake, utilization, and storage of glucose, amino acids, and fatty acids. It inhibits the breakdown of glycogen, protein, and fat. The α chain contains an intrachain disulfide bond.

Chemical cross-linking in combination with LC-MS/MS (XL-MS) is an emerging technology to obtain low-resolution structural (distance) restraints of proteins and protein complexes. These restraints can also be used to characterize protein complexes by integrative modeling of the XL-MS data, either

Insulin is a key hormone controlling glucose homeostasis. All known vertebrate insulin analogs have a classical structure with three 100% conserved disulfide bonds that are essential for structural stability and thus the function of insulin. It might be hypothesized that
