FRIEND MURINE LEUKEMIA VIRUS RECEPTOR-BINDING DOMAIN
Overview
An essential step in retrovirus infection is the binding of the virus to, its receptor on a target cell. The structure of the receptor-binding, domain of the envelope glycoprotein from Friend murine leukemia virus was, determined to 2.0 angstrom resolution by x-ray crystallography. The core, of the domain is an antiparallel beta sandwich, with two interstrand loops, forming a helical subdomain atop the sandwich. The residues in the helical, region, but not in the beta sandwich, are highly variable among mammalian, C-type retroviruses with distinct tropisms, indicating that the helical, subdomain determines the receptor specificity of the virus.
About this Structure
1AOL is a Single protein structure of sequence from Friend murine leukemia virus with NAG and ZN as ligands. Full crystallographic information is available from OCA.
