Analysis of effects of tRNA:message stability on frameshift frequency at the Escherichia coli RF2 programmed frameshift site.

Nucleic acids research - 25 Apr 1993

Curran J F

Abstract excerpt

The codon that is in-frame prior to +1 frameshifting at the E.coli prfB (RF2 gene) frameshift site is randomized to create thirty-two variants. These alleles vary 1000-fold in frameshift-dependent expression in fusions to lacZ. Frameshifting is more frequent at sites where the in-frame codon ends in uridine, as if third position wobble pairs to message uridine facilitate slippage into the +1 frame. Consistent...
