3.5.4.37 | 8-azaadenine in double-stranded RNA + H2O |
8-aza substitution at adenosine in various RNA substrates accelerates the rate of deamination at these sites by ADAR2 (2.8-17-fold). The magnitude of this effect depends on the RNA structural context of the reacting nucleotide |

A-to-I editing is a form of nucleotide substitution editing, because I is decoded as guanosine instead of A by ribosomes during translation and by polymerases during RNA-dependent RNA replication. Additionally, A-to-I editing can alter RNA structure stability as I:U mismatches are less stable than A:U base pairs. Both viral and cellular RNAs are edited by ADARs. A-to-I editing is of broad physiologic significance. Among the outcomes of A-to-I editing are biochemical changes that affect how viruses interact with their hosts, changes that can lead to either enhanced or reduced virus growth and persistence depending upon the specific virus |
