Diversity in mechanism and function of tRNA methyltransferases.

abstract：:Type II CRISPR-Cas9 systems require a small RNA called the trans-activating CRISPR RNA (tracrRNA) in order to function. The prediction of these non-coding RNAs in prokaryotic genomes is challenging because they have dissimilar structures, having short stems (3-6 bp) and non-canonical base-pairs e.g. G-A. Much of the t...
