Rop protein - global copy number inhibitor (SynORI framework)
Rop (also known as repressor of primer) is a small protein responsible for keeping the copy number of ColE1 and related bacterial plasmids low in E. coli. Inhibits plasmid replication of all SynORI framework plasmid groups non-specifically, also other ColE1 replicon plasmids.

Introduction
Biology
Repressor of primer (ROP) is a small dimeric protein that participates in ColE1 plasmid family copy number contro, by increasing affinity between two complementary RNAs - RNA I (Replication inhibitor) and RNA II (Replication activator). [1] By increasing affinity of the two RNA molecules Rop decreases the rate of of plasmid replication initiation events.
Rop dimer is a bundle of four tightly packed alpha helices that are held by hydrophobic interactions (Fig. 1).
