Figure 7From: Biophysical characterization and crystal structure of the Feline Immunodeficiency Virus p15 matrix proteinComparison of FIV p15 structures. (A) Superimposition of the structure of p15-Δ120 (chain A in blue, chain B in cyan) with interface 3 in the full-length p15 crystal (chain A in red, symmetric molecule in magenta). The superimposition was performed on the Cα of both chains A using COOT. N- and C- termini are indicated for each chain. (B) The close-up view of the interaction of the PEG molecule (magenta) with the Trp37 and Arg40 residues of p15-Δ120.Back to article page
