SDG-CW undergoes conformational change upon binding to H3K4me1.
A, superimposition of SDG8-CW in apo form (salmon) and SDG8-CW (green) in complex with H3K4me1 peptide (yellow). B, a stereoview of the conformational change at SDG8-CW η1 turn due to H3K4me1 peptide binding. Key residues involved in binding are shown in sticks. C, superimposition of the aromatic cage of SDG8-CW in apo form and in complex with H3K4me1 peptide. D, surface representation of the aromatic cage of SDG8-CW in apo form with residues shown in sticks. E, conformational change at SDG8-CW C-terminal α-helix due to H3K4me1 peptide binding.
