RiboMeth-seq data from Pyrococcus furiosus

Semiconductor sequencing of alkaline degraded total RNA from Pyrococcus furiosus annotated for ”The 23S ribosomal RNA from Pyrococcus furiosus is circularly permuted” published in Frontiers in Microbiology” Overall design: P. furiosus RNA was degraded at denaturing conditions into small fragments, long enough to be mapped by sequence alignment to the reference genome (20-40 nucleotides). The fragments were ligated to RNA oligos using a tRNA ligase that was mutated to remove its kinase activity, reverse transcribed and the cDNA used as input for Ion semiconductor sequencing. The first and last nucleotides of the inserts were recorded using the full sequence for mapping and the read-ends plotted against the sequence. 2'-O-Methylated RNA positions are protected from cleavage, and read ends from such positions are therefore underrepresented compared to the surrounding positions.
