Different stop codon usage in two pseudohypotrich ciliates.

چکیده
Based on rRNA phylogeny, morphologic and morphogenetic characters, two major groups of hypotrich ciliates can be distinguished: euhypotrichs and pseudohypotrichs. Through the sequencing of actin genes, we show here that, interestingly, the pseudohypotrichs Dyophrys sp. and Euplotes vannus have a different stop codon usage. In fact, the stop codon usage of the former species resembles that of euhypotrichs. This unexpected result is used to discuss the origin and acquisition of genetic code deviations in ciliates.

Stop codon recognition in ciliates: Euplotes release factor does not respond to reassigned UGA codon.
In eukaryotes, the polypeptide release factor 1 (eRF1) is involved in translation termination at all three stop codons. However, the mechanism for decoding stop codons remains unknown. A direct interaction of eRF1 with the stop codons has been postulated. Recent studies focus on eRF1 from ciliates in which some stop codons are reassigned to sense codons. Using an in vitro assay based on mammali...
متن کاملShifty Ciliates Frequent Programmed Translational Frameshifting in Euplotids
Recent work suggests that there is a high frequency of programmed +1 translational frameshifting in ciliates of the Euplotes genus. Frequent frameshifting may have been potentiated by stop codon reassignment, which is also a feature of this group.
متن کاملConsequences of stop codon reassignment on protein evolution in ciliates with alternative genetic codes.
Tetrahymena thermophila and Paramecium tetraurelia are ciliates that reassign TAA and TAG from stop codons to glutamine codons. Because of the lack of full genome sequences, few studies have concentrated on analyzing the effects of codon reassignment in protein evolution. We used the recently sequenced genome of these species to analyze the patterns of amino acid substitution in ciliates that r...
متن کاملEvolution of eukaryotic translation elongation and termination factors: variations of evolutionary rate and genetic code deviations.
Translation is carried out by the ribosome and several associated protein factors through three consecutive steps: initiation, elongation, and termination. Termination remains the least understood of them, partly because of the nonuniversality of the factors involved. To get some insights on the evolution of eukaryotic translation termination, we have compared the phylogeny of the release facto...
متن کاملThe molecular basis of nuclear genetic code change in ciliates
BACKGROUND The nuclear genetic code has changed in several lineages of ciliates. These changes, UAR to glutamine and UGA to cysteine, imply that eukaryotic release factor 1 (eRF1), the protein that recognizes stop codons and terminates translation, changes specificity. Here we test whether changes in eRF1 drive genetic code evolution. RESULTS Database sequence analysis reveals numerous geneti...
