Function and Biology Details

Reactions catalysed:
(1a) S-adenosyl-L-methionine + G(5')pppAACA-[mRNA] = S-adenosyl-L-homocysteine + G(5')pppAmACA-[mRNA]
Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1)
(1a) (5')pppAACA-[mRNA] + (protein L)-L-histidine = diphosphate + (protein L)-L-histidyl-(5')phosphonato-AACA-[mRNA] + H(2)O
