Retron Msr RNA
... present in many bacteria called multicopy single-stranded DNA (msDNA) ... carrying three loci, msr, msd, and ret, that are involved in msDNA synthesis ... The DNA portion of msDNA is encoded by the msd gene, the RNA portion is encoded by the msr gene, while the product of the ret gene is a reverse transcriptase ...
Multicopy Single-stranded DNA
... Multicopy single-stranded DNA (msDNA) is a type of extrachromosomal satellite DNA that consists of a single-stranded DNA molecule covalently linked via a 2'-5'phosphodiester bond to an internal ... The coding region for msDNA, called a "retron", also encodes a type of reverse transcriptase, which is essential for msDNA synthesis ... Before the discovery of msDNA in myxobacteria, a group of swarming, soil-dwelling bacteria, it was thought that the enzymes known as reverse transcriptases (RT) existed only in eukaryotes and viruses ...
