'''CRYSTAL STRUCTURE OF THERMOTOGA MARITIMA RIBOSOME RECYCLING FACTOR, RRF'''
===CRYSTAL STRUCTURE OF THERMOTOGA MARITIMA RIBOSOME RECYCLING FACTOR, RRF===




==Overview==
<!--
Ribosome recycling factor (RRF), together with elongation factor G (EF-G), catalyzes recycling of ribosomes after one round of protein synthesis. The crystal structure of RRF was determined at 2.55 angstrom resolution. The protein has an unusual fold where domain I is a long three-helix bundle and domain II is a three-layer beta/alpha/beta sandwich. The molecule superimposes almost perfectly with a transfer RNA (tRNA) except that the amino acid-binding 3' end is missing. The mimicry suggests that RRF interacts with the posttermination ribosomal complex in a similar manner to a tRNA, leading to disassembly of the complex. The structural arrangement of this mimicry is entirely different from that of other cases of less pronounced mimicry of tRNA so far described.
The line below this paragraph, {{ABSTRACT_PUBMED_10600747}}, adds the Publication Abstract to the page
