Figure 3
An interaction map of the VASH1c N-terminal region. (a) Heterotetramer. VASH1 chain D is shown as a structural formula colored magenta. Chains A and D are VASH1 and chain E is SVBP. (b) The PDB entry 6j7b heterodimer. VASH1 chain A is displayed as a structural formula colored dark gray. Chain B is SVBP. (c) The PDB entry 6ocf heterodimer. VASH1 chain A is displayed as a structural formula colored light gray. Chain B is SVBP. Intramolecular and intermolecular interactions of the N-terminal region are analyzed and shown in the 2D diagram. Interacting amino acids are shown in a circle with chain ID and residue numbers. The circles are colored according to the following scheme. Attractive charge interaction, orange; hydrogen bond, green; π–σ interaction, purple; π–π T-shaped interaction, magenta; alkyl–π-alkyl interaction, pink. The size of the blue shadow of an atom or amino-acid residue corresponds to the degree of solvent accessibility.
