Name: Enterobacteria phage MS2
Virus [1]
Name: Enterobacteria phage MS2
Scientific name: Enterobacteria phage MS2
Isolate: SPECIES
Details: The viral stock was obtained from ATCC (ATCC number 15597-B1) and cultured in Escherichia coli strain C-3000 (ATCC 15597).
Natural host [1]
Molecular weight
Experimental Theoretical Method
- 3 MDa -
Virus Shell [1]
Name Diameter triangulation
Capsid 270.0 Å 3
Complex [4]
Name: capsid shell of Enterobacteria Phage MS2
Details: The capsid of MS2 is composed of 178 copies of the coat protein and one single copy of the maturation protein.
Natural source [1]
Molecular weight
Experimental Theoretical Method
- 2 MDa -
Name: coat protein of Enterobacteria Phage MS2
Details: The 178 copies of the coat protein are organized as 89 dimers in a T=3 icosahedral lattice.

Molecular weight
Experimental Theoretical Method
- 14 kDa -
Name: maturation protein of Enterobacteria Phage MS2
Details: The single copy of maturation protein in the capsid shell of MS2 is located at one of the 2-fold symmetry axes and it replaces a coat protein dimer at this position.

Name: the ssRNA genome of Enterobacteria Phage MS2
Details: The genome of MS2 is a single-stranded RNA with 3569 bases. Our asymmetric cryoEM reconstruction of the MS2 virion shows that its ssRNA genome is well organized and has multiple contacts with the capsid shell via tens of RNA stem-loop structures.

Protein [2]
Name: Capsid protein
Number of copies: 8
Details: The capsid of MS2 contains 178 copies of the coat protein arranged as 89 dimers in a T=3 icosahedral lattice. Structure of the capsid has been solved by crystallography with icosahedral symmetry applied (PDB ID 2MS2, also included as chains A, B, C in this model). Chains D, E, F, G, H are coat proteins that have slightly different structures in the asymmetric cryoEM reconstruction compared to the crystallographic structure. Structures of the other 170 copies of the coat protein are the same with 2MS2, and thus are not included due to the limited number of chain IDs.

Name: Maturation protein
Number of copies: 1
Details: The capsid of MS2 contains a single copy of the maturation protein. Our structure shows that it replaces a coat protein dimer at one of the 2-fold icosahedral symmetry axes. Function of the maturation protein is to attach the MS2 virion to the host (E. coli) F-pili and deliver the ssRNA viral genome into the host during infection. of the icosahedral capsid. 178 copies of the coat protein arranged as 89 dimers in a T=3 icosahedral lattice.
