    The solution conformations of analogues of initiator and elongator tRNA anticodon stem-loops have been compared by NMR. The data indicate that both have conformations closely similar to those reported for crystalline elongator tRNAs. The two loops differ in their dynamics, however: that of the elongator analogue is more flexible than its initiator counterpart. The anticodon stem-loops of initiator tRNAs are more likely to be distinguished from those of elongator tRNAs during initiation on the basis of their distinctive stem sequences, than they are by differences in the conformations of their anticodon loops.
