Figure 7.
Figure 7. Focus on the tertiary interactions in the E. coli
Cys-tRNA^Cys molecule by (a) a stereographic representation and
(b) a schematic clover leaf diagram. Residue numbers refer to
the yeast tRNA^Phe standard, thus residues 17 and 47 are missing
(see Figure 1b ). The acceptor stem has been omitted from (a)
for clarity and the schematic diagram in (b) includes only the
base–base interactions. Further, the variable loop in (b) has
been wrapped into the clover leaf center to indicate the unique
role of A46 in the tertiary interactions. Colour codes are as in
Figure 2 . Part (b) was produced using ‘The Gimp’
(http://www.gimp.org).
