Crystallographic Study of an Adenovirus-Induced Protein Crystal in KB cells: a structural model

By Alain Lifchitz, Alexandre Rimsky, Gérard Torpier and Pierre Boulanger

Abstract

Copyright © International Union of CrystallographyThe physical parameters of a protein crystal induced by adenovirus type 5 in KB cells were determined from images of positively contrasted, sectioned intranuclear crystals. Fourier transforms of digitized images showed that the net appearing on transverse sections of the crystals, thus far considered as hexagonal, was in fact pseudohexagonal, rectangular. The three-dimensional characteristics of the crystal unit cell were: a0= 630, b0= 1200, c0=900 Å; alpha=gamma=90, beta=95.5°. The space group was P21. The asymmetric unit of the crystal was found to consist of a tubule centred by a densely stained tubular filament; its calculated molecular weight was 130 MDaltons. A three-dimensional model was reconstructed from the crystallographic data
