Rop protein (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''. Structurally, Rop is a homodimeric four-helix bundle protein formed by the antiparallel interaction of two helix-turn-helix monomers. The Rop protein's structure has been solved to high resolution. Due to its small size and known structure, Rop has been used in protein design work to rearrange its helical topology and reengineer its loop regions. In general, the four-helix bundle has been extensively used in de novo protein design work as a simple model to understand the relationship between amino acid sequence and structure. ==References== # #
