Dictionary » C » Capsid CapsidCapsid a protein coat that covers the nucleoprotein core or nucleic acid of a virion. Commonly shows icosahedral symmetry and may itself be enclosed in an envelope (as in the Togaviridae). The capsid is built up of subunits (some integer multiple of 60, the number required to give strict icosahedral symmetry) that self assemble in a pattern typical of a particular virus. The subunits are often packed, in smaller capsids, into 5 or 6 membered rings (pentamers or hexamers) that constitute the morphological unit (capsomere). The packing of subunits is not perfectly symmetrical in most cases and some units may have strained interactions and are said to have quasi equivalence of bonding to adjacent units. A variety of leaf bug.The outer covering of protein surrounding the nucleic acid of a virus.The protein coat that surrounds the dna or mrna of a virus. ![]()

some general capsid questionsWhat kind of proteins are the capsid shells made of? Will a collection of capsid proteins in soln' generally form an icosahedral (or other geometric shape, depending on protein..) shape; Will they from encapsulating shapes on their own? ...

Re: Viral Enzymes... for RNA viruses). These are then packed into the viral particle during the viral assembly. So, because they already carry the enzyme within the capsid, it is ready to use when the virus offloads its "cargo" into their target cell. In the cell, all parts of the virus are then produced ...

Viral Enzymes... so I am re-posting this here ) For the viruses that must carry a specific enzyme (eg. viruses with ssDNA, -ssRNA genomes): 1. It is carried in the capsid AND coded for in their genomes, right? 2. since they need this enzyme before they can use their genome, how do they ensure that a lot is transcribed? ...
