Comprehensive Phylogenetic Analysis of Bacterial Reverse Transcriptases
Much less is known about reverse transcriptases (RTs) in prokaryotes than in eukaryotes, with most prokaryotic enzymes still uncharacterized. Two surveys involving BLAST searches for RT genes in prokaryotic genomes revealed the presence of large numbers of diverse, uncharacterized RTs and RT-like sequences. Here, using consistent annotation across all sequenced bacterial species from GenBank an...
متن کاملA diversity of uncharacterized reverse transcriptases in bacteria
Retroelements are usually considered to be eukaryotic elements because of the large number and variety in eukaryotic genomes. By comparison, reverse transcriptases (RTs) are rare in bacteria, with only three characterized classes: retrons, group II introns and diversity-generating retroelements (DGRs). Here, we present the results of a bioinformatic survey that aims to define the landscape of R...

متن کاملAn Unexplored Diversity of Reverse Transcriptases in Bacteria.
Reverse transcriptases (RTs) are usually thought of as eukaryotic enzymes, but they are also present in bacteria and likely originated in bacteria and migrated to eukaryotes. Only three types of bacterial retroelements have been substantially characterized: group II introns, diversity-generating retroelements, and retrons. Recent work, however, has identified a myriad of uncharacterized RTs and...
متن کاملVancouver , BC , Canada Background Activity of Reverse Transcriptases
images were scanned using a Hewlett Packard 6300 dpi resolution scanner. The MeP footprint of androgen receptor cooperatively bound to DNA revealed for the first time guanines that became hypersensitive to DMS methylation (Figure 1). Since DMS normally methylates guanines uniformly, the hypermethylation of guanine indicates local distortion to the DNA. Therefore, MeP is an ideal footprinting m...
