The redox state of the disulfide bonds in beta 2 subunit was processed as described by Chiu (2024) Methods Mol Biol (DOI: 10.1007/978-1-4939-9187-7_4). WebDisulfide bond plays a very much important role to form the secondary structure of protein. It is basically a covalent type bond. Disulfide bond is formed by the oxidation of sulfyhydryl or thiol group (S-H group), present only in Cysteine amino acid (non essential amino acid). It is also known as S-S bond . Disulfide bond is denoted by R-S-S-R1.
WebDisulfide bonds are covalent bonds formed by the oxidation of cysteine side-chains and are present in at least 20% of proteins, but their function is not fully understood. In our study, we primarily use molecular dynamics simulations to analyze their role in stability and activity. Using three different
