title: Catalysis by a prebiotic nucleotide analog of histidine.
abstract: A ribosylated derivative of adenine, N6 ribosyl adenine, likely to have formed under prebiotic synthesis conditions, is shown to be as active as histidine in the model reaction of p-nitrophenyl acetate hydrolysis. This property widens the range of reactions accessible to RNA catalysis.
