Novel Small Stable RNAs of Mycoplasma capricolum

Two stable RNA species and their genes have been isolated fromMycoplasma capricolum, and the nucleotide sequences have beendetermined by partial RNA sequencing and sequencing of the genes.The RNAs are 92 and 105 nucleotides in length, respectively.The two RNAs reveal no sequence similarity to any stable RNAso far reported, indicating that these are novel RNA species.The RNAs, designated MCS2 and MCS3 RNA, exist in small amountsin the soluble fraction of the cell extract.
