Non-cognate template usage and alternative priming by a group II intron-encoded reverse transcriptase.

Abstract excerpt

Group II introns are retroelements that site-specifically insert into DNA through homing. They are also implicated in related phenomena such as ectopic site insertions and precise intron deletions, but little is known about how group II intron reverse transcriptases (RTs) interact with non-cognate substrates. Here we show that wild-type aI2 RT readily reverse transcribes non-cognate RNAs in mitochondrial RNP...
