Abstract

Anticodon nuclease is a bacterial restriction enzyme directed against tRNALv8. We report that anticodon nuclease also cleaves mammalian tRNA^Lys molecules, with preference and site specificity shown towards the natural substrate. Expression of the anticodon nuclease core polypeptide PrrC In HeLa cells from a recomblnant vaccinia virus elicited cleavage of intra-cellular tRNA^Lys,3The data justify an inquiry into the possible application of anticodon nuclease as an inhibitor of tRNA^Lys,3-primed HIV replication. They also indicate that the anticodon region of tRNA^Lys is a substrate recognition site and suggest that PrrC harbors the enzymatic activity.
