WebJan 11, 2016 · Attempts to identify DNA catalysts for protein glycosylation resulted in the DNA enzymes that catalyze self-glycosylation near the 5′-terminus of the catalytic region. A new selection strategy that prevents the selection of self-glycosylating deoxyribozymes was designed. That strategy will be implemented in future selection experiments. Web‘It took us a long time to realise that there was no protein and it was the RNA itself that was the catalyst.’ He set about to prove this ‘heresy’ by expressing the same RNA molecule in Escherichia coliand showing that no contaminating Tetrahymenaprotein could be responsible for the reaction.
