Sentence examples for main chain nitrogen from inspiring English sources

The Glu7 residue of upain-1 forms hydrogen bonds with the main chain nitrogen atoms of residues 4, 5, and 6 of upain-1, and is also critical for maintaining the active conformation of upain-1.

The following boophilin residue, BN18, interacts through its side chain with the main chain nitrogen atom of TG219 and the carboxyl oxygen of TE146, the latter via a solvent molecule.
