Metal-catalysed cross-couplings and macrocyclizations of linear precursors that contain linkages other than peptide bonds are beyond the scope of this Review.

A trans arrangement of the nitrogens in either the isopeptide or α-peptide would cause the P1′ substituent (on the C-terminal side of the scissile peptide bond) to clash with the loop ...

Chemists explain why dinosaur collagen may have survived for millions of years The researchers identified an atomic-level interaction that prevents peptide bonds from being broken down by water ...
