Figure 6.
Fig. 6. Recognition of tRNA moiety by AlaX. Shown is a
surface potential representation of PhoAlaX (A) and ThrRS-N2 (8)
(B), where acidic and basic potentials are represented in red
and blue, respectively. The serine and the SerA76 are shown as
stick models. The region corresponding to the hairpin motif is
circled with a green dashed line. (C) Superposition of PhoAlaX
(red tube) on ThrRS-N2–tRNA (yellow tube). (Left) The overview
of the superposed image. The third base pair is shown as a green
bar. (Right) An enlarged view of the hairpin motif interacting
with tRNA.
