Retroviral integrase protein and intasome nucleoprotein complex structures

Figure 5 Superposition of prototype foamy virus strand transfer complex, Rous sarcoma virus strand transfer complex, and mouse mammary tumor virus cleaved donor complex structures with respect to vDNA and tDNA. For simplicity, integrase content is either partially transparent or omitted. Color-coding is as following: PFV DNA: Black; RSV DNA: Grey; MMTV DNA: Purple. 90° rotations show different angles of the intasomes. PDB accession codes: PFV STC: 3OS0, RSV STC: 5EJK, MMTV CDC: 3JCA. PFV: Prototype foamy virus; RSV: Rous sarcoma virus; MMTV: Mouse mammary tumor virus; STC: Strand transfer complex; CDC: Cleaved donor complex.
