研究结论

Date Results Publications
2019-07-13 10:45:00 Study used time-resolved cryo-EM to visualize transient compact forms of RF1 and RF2 at 3.5 and 4 A resolution, respectively, in the codon-recognizing ribosome complex on the native pathway. About 25% of complexes have RFs in the compact state at 24 ms reaction time, and within 60 ms virtually all ribosome-bound RFs are transformed to their extended forms. 31189921
2019-04-20 11:30:00 Ribosome termination complexes that carry two factors, RF1-RF3 or RF2-RF3, are dynamic and fluctuate between non-rotated and rotated states, whereas each factor alone has its distinct signature on ribosome dynamics and conformation. 29889659
2018-05-12 10:57:00 both RF1 binding and RF2 binding are sufficient to shift the population of posthydrolysis ribosome complexes from primarily the rotated to the nonrotated state only when a cognate stop codon is present in the A-site. 29499110
2017-05-27 10:52:00 Data show that peptide chain release factor RF-3 (RF3) hydrolyzes GTP and dissociates from the ribosome before peptide chain release factor RF-1 (RF1)dissociation. 27779391
2016-08-20 12:06:00 These results indicate that RF1 undergoes a large conformational change from a closed to an open form upon binding to the ribosome. 26827724
