![]() | ![]() タイトル: The crystal structure of coxsackievirus A21 and its interaction with ICAM-1. 著者: Chuan Xiao / Carol M Bator-Kelly / Elizabeth Rieder / Paul R Chipman / Alister Craig / Richard J Kuhn / Eckard Wimmer / Michael G Rossmann / ![]() 要旨: CVA21 and polioviruses both belong to the Enterovirus genus in the family of Picornaviridae, whereas rhinoviruses form a distinct picornavirus genus.

Nevertheless, CVA21 and the major group of human rhinoviruses recognize intercellular adhesion molecule-1 (ICAM-1) as their cellular receptor, whereas polioviruses use poliovirus receptor. The crystal structure of CVA21 has been determined to 3.2 A resolution. Its structure has greater similarity to poliovirus structures than to other known picornavirus structures. Cryo-electron microscopy (cryo-EM) was used to determine an 8.0 A resolution structure of CVA21 complexed with an ICAM-1 variant, ICAM-1(Kilifi). The cryo-EM map was fitted with the crystal structures of ICAM-1 and CVA21. Significant differences in the structure of CVA21 with respect to the poliovirus structures account for the inability of ICAM-1 to bind polioviruses. The interface between CVA21 and ICAM-1 has shape and electrostatic complementarity with many residues being conserved among those CVAs that bind ICAM-1. | |||||||||

HETEROGEN THE N-TERMINAL OF VP4 (CHAIN 4) IS MYRISTYLATED WHICH MEANS THE MYR IS COVALENTLY LINKED TO THE GLY OF VP4. THEREFORE, THE O2 ATOM ON MYR IS EXPECTED TO BE MISSING AFTER MYRISTYLATED. | |||||||||
