*'''ATP-dependent helicase Rho''' is a protein involved in termination of transcription in prokaryotes. Rho binds to the transcription terminator site on single-stranded RNA. Rho forms a ring-shaped hexamer and advances along the mRNA until it reaches the RNA polymerase and causing it to dissociate from the DNA and end transcription.<br /> | *'''ATP-dependent helicase Rho''' is a protein involved in termination of transcription in prokaryotes.

*'''ATP-dependent helicase RuvB-like 1''' (RuvBL1) or '''TIP49''' is a human protein which forms hexamers. The hexamer forms dodecamer upon association with RuvBL2 or '''TIP48''' and the complex possesses single-stranded DNA-stimulated ATPase and helicase activities. | *'''ATP-dependent helicase RuvB-like 1''' (RuvBL1) or '''TIP49''' is a human protein which forms hexamers.
