Hello all, I was wondering if I had a pool of aminoacylated RNA oligos with an amino acid covalently attached to their 3' end, and a pool of "target" RNAs, is there an enzyme that could ligate the amino group of the amino acid to the 5' phosphate of the target RNAs? This ligation has been shown to proceed non-enzymatically on a template, but I was hoping to be able to do it with a diverse set of unknown sequences, such that they could not be templated. Thanks very much.
