Sentence examples for main chain hydrogen from inspiring English sources

The main chain hydrogen bonding pattern in parallel β-sheets means that, for each residue pair, only one of the residues is involved in main chain hydrogen bonding with the strand containing the partner residue.

The design allows the peptide backbone to change direction with a minimal loss of main chain hydrogen bonds.

Side chains within a contact distance of 4 Å are shown as sticks, while main chain hydrogen bonding contact atoms are shown as small spheres.

G514 and G516 are involved in the side chain - main chain hydrogen bonding with E484, while F513 and D534 residues are involved in the main chain-main chain hydrogen bonding (Figure 11) [54].

It has been suggested that PPII helices could be stabilized by water mediated main chain hydrogen bonds (in the absence of main chain-main chain H-bonds), as they also tend to have a regular pattern of hydrogen bonds with water [30].

It would be useful to add some comment about how main chain hydrogen bonding is affected.

Even though BbpThr582 and Leu584 could interact with the peptide by two pairs of main chain-main chain hydrogen bonds (Fig. 3C), the replacement to alanine might serve a similar role instead of breaking the interaction with the peptide according to the results here.

Few main chain-main chain & side chain-main chain hydrogen bonds were found (data not shown).

For the V1D mutant, one additional side chain-main chain hydrogen bond was predicted between Asp1 and Gln2.

This appears to release stored strain energy in the structure, as it leads to a new conformation where the D6.43 carboxylate group moves towards the now-bound negatively charged phosphate (Fig. 5b), the 6.43 region does not form main-chain hydrogen bonds, and the pumped ion becomes localized at the ionic gate.

At the dimer interface, hydrophobic interactions formed among the side chains of Erh1 residues Ile11, Leu13, Trp25, Leu72, Tyr81, and Pro83; two main-chain hydrogen bonds between the carbonyl oxygen and amide nitrogen atoms of Tyr81 on strand 4 of each monomer; side-chain hydrogen bonds between Arg23 and Asp27 of each monomer (Fig. 2c).
