Question
Gallivan and Dougherty's study of 593 structures in the Protein Data Bank found that these interactions occur on average once every 77 residues, though most of them make only small contributions to overall stability. For 10 points each:
[10h] Name this type of non-covalent interaction between a positively-charged monopole and a molecular structure with a quadrupole moment.
ANSWER: cation-pi interaction
[10m] The monopole-quadrupole cation-pi interaction can be contrasted with these quadrupole-quadrupole interactions, which can occur in proteins with ty·ro·sine, tryp·to·phan, and phenyl·alanine residues.
ANSWER: pi-pi stacking
[10e] In proteins, this term names non-covalent bonds between residues with opposite charges. In an electrochemical cell, this term names a structure that connects the anode and cathode to complete the circuit and enable continuous charge flow.
ANSWER: salt bridges
