Hi all, I am after as small an origin as possible (for a plasmid rescue
system). ColE1 seems to be 900 or so bps, we have some old vectors with
pBR oris of 580bps, and I've just found a ref (Thomas et al Mol Gen Genet
1981 1-16 that talks of oriRK2 a 393bp fragment but this requires trans
acting factors to be present in the genome of the bacteria or on another
Is this the smallest ori? Can anyone point me in the right direction for
some newer refs?
