Alignment of ORF56 from pRN1
with copy control proteins (CopG) from other rolling circle plasmids.
ORFC from pWVO1 (accession no. JQ1198), CopA from ppsc22 (accession
no. X95843), Cop protein from pSBO2 (accession no. AB021465), CopG
(formerly RepA) from pLS1 (accession no. A25599), ORF52 from pRN2
(accession no. U93082), Cop-6 from pE194 (accession no. M59209)
and ORF56 from pRN1 (accession no. U36383). DNA binding has been shown
for CopG from pLS1 (26) and Cop-6 (27). The GOR IV secondary structure
prediction (c, coil; e, β-strand; h, α-helix) is given below the alignment.
