In the open subunit of the ternary complex of ApIDH, the 2'-phosphate group of [NADP.sup.+] is indeed interacted with the corresponding Tyr349 and Arg400 and Lys348 is situated close (6.2 [Angstrom]) to it (Figure 5(b)).
As it was expected tetrakis [Eu.sup.3+] complex C2 exhibits higher intensity for [.sup.5][D.sub.0][right arrow][.sup.7][F.sub.2] transition than ternary complex C1 in THF and in solid-state due to fact, that coordination sphere of [Eu.sup.3+] in C2 is filled with four DBM ligands, which efficiently transfer the excitation energy to central metal ion and also provides better shielding of metal ion from surrounding environment.

The ternary complex (eIF2GTP-met-tRNAi) associated with a 40S ribosomal subunit is then recruited to the 5' end of the mRNA via a critical link to eIF4G (captured at the cap via eIF4E) mediated by eIF3, forming the 43S preinitiation complex.
