Example sentences for: yrh

How can you use “yrh” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Interestingly, the PSI-BLAST searches started with the sequences of the RDRP module of the RDRPs and the YRH proteins consistently retrieved the β' subunits of DDRPs, albeit at statistically not significant E-values.

  • The bacteriophage YRH proteins show no specific relationship with the RDRPs from any one eukaryotic lineage, arguing against a recent lateral transfer from eukaryotes to the phages.

  • Thus, these comparisons identify previously undetected prokaryotic homologs of the eukaryotic RDRPs, the YRH proteins, which probably also have RNA-dependent RNA polymerase activity.

  • Should that be the case, the YRH proteins could be late surviving derivatives of these ancient enzymes, which apparently have been shunned from cellular life forms during the evolution of prokaryotes.

  • Nevertheless, the extended similarity between the YRH and RDRP sequences and the presence of potential nucleic-acid-binding modules, such as a C-terminal Zn-ribbon in the SpβC2 YonO protein, suggest that the YRH proteins also have a RNA polymerase activity.
