The first diffraction pattern of a crystalline single-stranded DNA virus has been obtained. Canine parvovirus was crystallized in a monoclinic P21 unit cell with a = 264.4 A, b = 350.3 A, c = 267.8 A and beta = 90.86 degrees (1 A = 0.1 nm). The diffraction pattern extends to at least 2.8 A resolution. Packing of the particles suggests that they have a diameter around 257 A, in excellent agreement with the reported molecular weight of 5.5 x 10(6).
已获得一种结晶单链DNA病毒的首个衍射图谱。犬细小病毒在单斜P21晶胞中结晶，其a = 264.4埃，b = 350.3埃，c = 267.8埃，β = 90.86度（1埃 = 0.1纳米）。衍射图谱的分辨率至少达到2.8埃。颗粒的堆积情况表明它们的直径约为257埃，与报道的5.5×10⁶的分子量高度吻合。
