Figure 3. The four-strong Mg2+-binding sites in yeast
tRNA^Phe. (a) Mg2+-binding site 1, (b) Mg2+-binding site 2, (c)
Mg2+-binding site 3, (d) Mg2+-binding site 4. For each site, a
stereo representation with combined, sigmaa-weighted |2F[o] -
F[c]| electron density map contoured at 1.0 s is shown on the
left; on the right, the same binding sites are shown
colour-coded according to temperature factors. Conventions are
as described in legend to Figure 2. Direct bonds ( slant
2.1 Å) involving Mg2+ ions are shown as continuous black
lines, with the exception of the longer range contacts made by
Mg2+ 1 (a), which are depicted as broken black lines. The bases
of nucleotides G18 and G19 have been omitted for clarity from
(c).
