The bacteriophage A2 major tail protein gene utilizes a 1 translational frameshift to generate two structural polypeptides. Frameshifting is promoted by a slippery sequence and an RNA pseudoknot located 3' of the gene. The major head gene presents a similar recoding ability. A2 is the only phage described with two 1 frameshifts.
