Ribosome recycling factor

Function Ribosome recycling factor (RRF) acts in releasing the ribosome from mRNA after completion of protein synthesis. RRF splits the ribosome into its small and large subunits. RRF is used together with elongation factor G in achieving this separation. RRF is a structural mimic of tRNA but binds to the ribosome differently than the A-site, P-site or E-site tRNA. .
