Insulin is a polypeptide hormone that consists of two polypeptide chains, A and B, linked by two interchain and one intrachain disulfide bond. From:Trends in Molecular Medicine,2002 Chapters and Articles You might find these chapters and articles relevant to this topic. ...
The present invention relates to a polypeptide that forms one part of a two- part linker in which the polypeptide spontaneously forms an isopeptide bond with a peptide tag, the second part of the two-part linker. Nucleic acid molecules encoding the polypeptide, vectors comprising said nucleic ...
and tissue regeneration. It is secreted as a single inactive polypeptide and is cleaved by serine proteases into a 69-kDa alpha-chain and 34-kDa beta-chain. A disulfide bond between the alpha and beta chains produces the active, heterodimeric molecule. The protein belongs to the lasminogen su...

The presence of a fusion peptide (FP) is a hallmark of viral fusion glycoproteins. • Structure–function relationships underlying FP conservation remain greatly unknown. • FPs establish interactions satisfying their folding within pre-fusion glycoproteins. ...
of said amino acid moiety of the compound to form said peptide bond. Preferably the formation of said peptide bond is carried out as a solid phase peptide synthesis step in which the forming peptide compound is attached to a resin. Preferably the entire polypeptide is built up by a step wis...
It should be appreciated that an internalization peptide may be linked to an active peptide via an amide bond to form a fusion peptide, but they may also be linked via other suitable means, such as chemical bonding. Coupling of two components can be achieved with a coupling agent or a conj...
