1.A.83.1.5
The structure of the polyomavirus internal protein including a synthetic fragment of 18 aas in which the C-terminal sequence is derived from Vp2 of 319 aas and a 283 aa fragment of the major capsid protein Vp1, which has a full length of 384 aas, is known (1CN3), providing insight into their involvement in viral entry (Chen et al. 1998). The fragments of Vp1 and Vp2, present in this complex, are derived by proteolysis from two large full length proteins, Vp1 and Vp2 as noted above. These full length proteins are included here under TC# 1.A.83.1.5. There are multiple structures reported in PDB of the Vp1 protein: 1CN3, 1SID, 1SIE, 1VPN, 1VPS, 5CPZ, 5CQ0.
