“…Examples are included in Figure 3. Some of them follow Moody's 7,8 (oblate for N = 67 in Figure 3h) and Luque and Reguera's 9 rules (N = 46 and 48 in Figure 3e and f, respectively), but others are completely new (N = 40 with tetrahedral symmetry in Figure 3a, N = 63 with D 3 symmetry in Figure 3g, or the asymmetric N = 45 in Figure 3d). Figure S-4 shows particularly stable capsids for N in the neighbourhood of the T = 4 capsid (e.g.…”

“…The simple geometrical construction model introduced by Caspar and Klug (CK) 2 to explain the architecture of icosahedral viruses is a milestone in modern virology. Generalizations of the CK rules properly account for the geometry of some exceptional icosahedral capsids [3][4][5][6] and other elongated virus capsids that share coordination numbers with the icosahedral ones [7][8][9] . Recent work [10][11][12] provides important further development about the effect of the geometrical and topological constraints on the capsid structure.…”

“…Whereas the soc protein helps to stabilize the capsid against extremes of pH and temperature, hoc only has a marginal effect on head stability (11, 12). However, both proteins are dispensable for the head morphogenesis and phage infection.The mature T4 head is a prolate icosahedron elongated along a fivefold axis (7,9,13,14). The surface of the prolate icosahedron is composed of two end caps, each made of five equilateral triangular facets and connected by an elongated midsection made of 10 triangular facets ( Fig.…”

“…It is a prolate icosahedron of triangulation number (T) = 13 (1, 2) elongated on its 5-fold axis of symmetry (3), with a length-to-width ratio of 1.37 (4). It is assembled on the Escherichia colh inner membrane as a core-containing prehead (5), which is matured to the finished head by a series of reactions that includes limited proteolysis of capsid and core proteins, expansion of the prehead shell lattice, and packaging of the phage DNA (6).…”
