Figure 2. Structure of CPV17 polyhedrin.

Figure 2

(a) Electron density around the ATP moiety contoured at 1.3 σ. (b) Cartoon of the CPV17 polyhedrin subunit coloured from blue to red, N terminus to C terminus that are denoted by spheres. Secondary structure elements are labelled and the ATP molecule shown as sticks. (c) Comparison of the CPV17 and CPV1 polyhedrin structures. The molecules were aligned with program SHP43. Both colour and tube thickness represent r.m.s. distance (r.m.s.d.) of equivalent C-alpha atoms (thin, blue: r.m.s.d.<1.0 Å, green, thicker: 1.0–2.5 Å, orange, thickest: >2.5 Å). Unaligned regions are coloured red and displayed with exaggerated thickness. Variable regions are labelled v1–v5 with the N- and C-terminal extensions of CPV1 drawn. (d) Comparison of variable regions between CPV17 (magenta) and CPV1 (cyan). (e) The interface between monomers (coloured differently) in the crystal is rich in tyrosines.
