Transcribed text From Image: 1.8 Two proteins bind each other noncovalently in an aqueous solution, with a total in teraction surface (i.e, the interface of both binding partners) of 500 À2. A pH change leads to conformational changes in both proteins, which results in a decrease of their using the empirical method described in the text.
Expert Chegg Question Answer:
1. 8 ) Here, two proteins bind each other noncovalently in an aqueous solution.
Reversible interactions of biomolecules are mediated by three kinds of non covalent bonds
1) electrostatic interaction
2) hydrogen bonds
3) Van der waals interaction
— In question they asked the nonpolar interaction energy, so
they are talking about van der waals interaction.
Van-der-waals interaction energy-
These interactions are highly distance dependent, decreasing in proportion to the sixth power of separation.
