Bromovirus coat protein (IPR002009)

Short name: Bromo_CP

Overlapping homologous superfamilies


Family relationships



This family consists of Bromovirus coat proteins. RNA-protein interactions stabilise many viruses and also the nucleoprotein cores of enveloped animal viruses (e.g. retroviruses). The nucleoprotein particles are frequently pleomorphic and generally unstable due to the lack of strong protein-protein interactions in their capsids.

The structure is known for Cowpea chlorotic mottle virus (CCMV) [PMID: 7743132]. It shows novel quaternary structure interactions based on interwoven carboxyterminal polypeptides that extend from canonical capsid beta-barrel subunits. Additional particle stability is provided by intercapsomere contacts between metal ion mediated carboxyl cages and by protein interactions with regions of ordered RNA.
