sid

Gene
sid
Protein
Glycoprotein 3
Organism
Enterobacteria phage P4
Length
244 amino acids
Function
Although P4 acquires its capsid proteins from helper phages such as P2, it possesses the ability to assemble capsids that are only one-third the size of the helper's capsid. The sid protein is responsible for the assembly of P4-sized shells. It forms a P4-specific scaffold with icosahedral symmetry on the outside of the procapsid-like particles.
