As translation proceeds, the nascent polypeptide chain passes through a tunnel in ... directly visualize density consistent with α-helix formation in the tunnel as well as the sites of ...

These four polypeptide chains form a symmetrical molecular structure ... this results in the formation of two identical fragments that contain the light chain and the VH (Variable Heavy chain ...

Each amino acid within this polypeptide chain has a different property ... Hydrolysis of ATP then initiates the formation of an enclosed state, called the folding-active state.

Llamas, unlike most mammals, produce antibodies composed of a single polypeptide chain ... cysteine-containing peptides due to unintended disulfide formation between the peptide and heavy chain ...
