Genes with sequence similarity to the yeast tRNAHis guanylyltransferase (Thg1) gene have been identified in all three domains of life, and Thg1 family enzymes are implicated in diverse processes, ranging from tRNAHis maturation to 5′-end repair of

Box C/D ribonucleoprotein (RNP) particles mediate O2′-methylation of rRNA and other cellular RNA species. In higher eukaryotic taxa, these RNPs are more complex than their archaeal counterparts, containing four core protein components (Snu13p, Nop5

Although 5S rRNA is a highly conserved and universal component of eubacterial, archaeal, chloroplast, and eukaryotic cytoplasmic ribosomes, a mitochondrial DNA-encoded 5S rRNA has so far been identified only in land plants and certain protists. This

In the ciliate protozoon, Tetrahymena pyriformis, mitochondrial protein-coding genes are highly divergent in sequence, and in a number of cases they lack AUG initiation codons. We asked whether RNA editing might be acting to generate protein sequence

U5 snRNAs in trypanosomatid protozoa do not contain the trimethylguanosine cap structures that are often targeted in snRNA isolation procedures. As a result, the trypanosomatids are not well represented in the database of available U5 snRNA sequences

Using PCR-based methods, we assembled two wheat cDNA sequences, wheat-G and wheat-C, that encode T3/T7 bacteriophage-like RNA polymerases (RNAPs) sharing 45% amino acid identity. In phylogenetic analyses using maximum likelihood, parsimony and distan

Comparative modeling of secondary structure is a proven approach to predicting higher order structural elements in homologous RNA molecules. Here we present the results of a comprehensive comparison of newly modeled or refined secondary structures fo

We have determined the sequence of the 1003-bp control region (also referred to as the ‘displacement-loop region’) and flanking tRNA genes in the mitochondrial DNA (mtDNA) of the rainbow trout, Oncorhynchus mykiss. This region has the same overal

Many genes inherited from the alpha-proteobacterial ancestor of mitochondria have undergone evolutionary transfer to the nuclear genome in eukaryotes. In some rare cases, genes have been functionally transferred in pieces, resulting in split proteins

Summary Resolving the global phylogeny of eukaryotes has proven to be challenging. Among the eukaryotic groups of uncertain phylogenetic position are jakobids, a group of bacterivorous flagellates that possess the most bacteria-like mitochondrial gen
