Positions 94-98 of the lactose repressor N-subdomain monomer-monomer interface are critical for allosteric communication.

Biochemistry - 5 Oct 2010

Zhan Hongli, Camargo Maricela, Matthews Kathleen S

Abstract excerpt

The central region of the LacI N-subdomain monomer-monomer interface includes residues K84, V94, V95, V96, S97, and M98. The side chains of these residues line the β-strands at this interface and interact to create a network of hydrophobic, charged, and polar interactions that significantly rearranges in different functional states of LacI. Prior work showed that converting K84 to an apolar residue or converting...
