ω-Conotoxin MVIIC is a peptide that inhibits other calcium ion subtype channels that pounce into the central nervous system of mammals. The sequence consists of 26 amino acids. The 6 Cys in the sequence form three pairs of disulfide bonds, and the peptide structure is quite stable. . There are four Lys in the ω-Conotoxin MVIIC sequence, but due to the presence of β-sheets, the side chain groups are encapsulated in the sequence. Therefore, the peptide has a lot of reactivity to biotinylation and has little effect on biological activity,Therefore, ω-Conotoxin MVIIC has great potential to become a raw material for medicine.
