The rate of cap removal from the alfalfa mosaic virus (A1MV) RNAs with tobacco acid pyrophosphatase (TAP) depends on the RNA species. At 37 degrees C and in the absence of divalent cation, RNA 3 reacts more slowly than the other three, which are decapped at similar rates. In the presence of magnesium, at 25 degrees C, TAP also discriminates against RNA 1. Thus the order of reactivity with TAP largely mimics the hierarchy of initiation efficiencies of the A1MV RNAs (Godefroy-Colburn et al., preceding paper in this journal). Our interpretation of these findings is that cap accessibility is what limits the rate of reaction with initiation factors as well as with TAP. In this hypothesis, translational discrimination between naturally capped messages would be related to the rate of 'breathing' of their 5' ends.
