Method: X-ray diffraction, Resolution 2.8Å Ligands: CA Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function CAPSD_BBV Capsid protein alpha self-assembles to form an icosahedral procapsid with a T=3 symmetry, about 30 nm in diameter, and consisting of 60 capsid proteins trimers. In addition, calcium ions are incorporated per capsid during assembly. The capsid encapsulates the two genomic RNAs. Capsid maturation occurs via autoproteolytic cleavage of capsid protein alpha generating capsid protein beta and the membrane-active peptide gamma (By similarity). Peptide gamma is a membrane-disrupting peptide produced by virus maturation, thereby creating the infectious virion. After penetration into the host cell, peptide gamma is probably exposed/released in endosomes, where it disrupts the endosomal membrane, facilitating translocation of viral RNA into the cytoplasm (By similarity).
