capsid

 [kap´sid]
the shell of protein that protects the nucleic acid of a virus; it is composed of structural units, or capsomers. According to the number of subunits possessed by capsomers, they are called dimers (2), trimers (3), pentamers (5), or hexamers (6).

cap·sid

(kap'sid),
Protein coat of a virus. See: virion.

capsid

/cap·sid/ (kap´sid) the shell of protein that protects the nucleic acid of a virus; it is composed of structural units, or capsomers.

capsid

(kăp′sĭd)
n.
The protein coat that constitutes the shell of a virus particle.

capsid

[kap′sid]
Etymology: L, capsa, box
the layer of protein enveloping the genome of a virion. A capsid is composed of structural units called capsomeres. Its symmetry may be cubic or helical.

capsid

A protein coat that covers the nucleoprotein core or nucleic acid (RNA, DNA) of a free virus particle or phage, which may have icosahedral symmetry and itself be enclosed in an envelope—e.g., Togaviridae. It is composed of an integer multiple of 60 subunits, which self-assemble in a pattern typical for a particular virus.

vi·ri·on

(vī'rē-on)
The complete virus particle that is structurally intact and infectious.

capsid

The protein coat that encloses the genome of a virus.

capsid

the protein coat of a virus.

Capsid

The outer protein coat of a virus.

capsid

the shell of protein that protects the nucleic acid of a virus; it is composed of individual morphological units called capsomers. For icosahedral viruses, there are two kinds of capsomers called pentamers, which occupy the 12 corner positions of the icosahedral shell, and hexamers, which occupy the face and edges. The number of hexamers varies between different viruses. The capsomers of helical viruses are composed of a single polypeptide and are also called protomers. All viruses of animals, except for poxviruses which have a complex structure, are minimally composed of a nucleocapsid which is the capsid surrounding the nucleic acid. In addition some viruses have an envelope surrounding the nucleocapsid.
