Short tail fibres consist of the single protein gp12. This protein forms a parallel, in-register, homo-trimer of 527 residues per subunit. 1ocy is a monomer of the short tail fibres. | |||
Gp12 can be divided into two fragments. One frgament with a mass of 33kDA and a second fragment with a mass of 45kDa. | |||
==The 33kDa fragment == | |||
The 33kDa fragment was generated in the presence of EDTA. This fragment contains the residues 85-395 and 518-527. The residues 397-517 are lacking. | |||
The 33kDa fragment can be further sub-divided into two subunits. The neck (residue 333-341) and the collar (residues 342-396 plus 518-527). The neck connects the body of the fibre to its C-terminal collar and receptor binding-site. It consists of a triple alpha-helix of residues 333-341. | |||
