STRUCTURE OF THE C-TERMINAL RECEPTOR-BINDING DOMAIN OF AVIAN REOVIRUS FIBRE SIGMAC, ZN CRYSTAL FORM.
Overview
Avian reovirus fibre, a homo-trimer of the sigmaC protein, is responsible, for primary host cell attachment. The protein expressed in bacteria forms, elongated fibres comprised of a carboxy-terminal globular head domain and, a slender shaft, and partial proteolysis yielded a carboxy-terminal, protease-stable domain that was amenable to crystallisation. Here, we show, that this fragment retains receptor-binding capability and report its, structure, solved using two-wavelength anomalous diffraction and refined, using data collected from three different crystal forms at 2.1 angstroms, 2.35 angstroms and 3.0 angstroms resolution. The carboxy-terminal globular, domain has a beta-barrel fold with the same overall topology as the, mammalian reovirus fibre (sigma1). However, the monomers of the ... [(full description)]
