Motion in 16S fragment of small ribosomal subunit (30S RNA) [16S]
[ jump to morphs ]
Classification Known RNA Motion [N-R-2]
Structures 1FJF subunit with proteins 1IBM subunit with bound tRNA and mRNA
Description Binding of m/tRNA induces some drastic local changes in the 16S RNA such as the A1492, A1493, and G530 which flip 180 degrees. The backbone also moves slightly. The morph linked below is the interpolation between the native 16S, and with mRNA and tRNA bound.
