the hierarchy of formation of native contacts of HIV–1–PR, the different gray levels corresponding to different time scales, while in Table \[table2\] are listed the parameters associated to the selected contacts. The picture that emerges is that local contacts within fragments 83–93, between residues 25–28 and in the beta–hairpin 42–58 form first. Then the beta–turns 15–18 and 65–70, again built of local residues. The next event is the assembly of the nucleus involving fragments 22–34 and 83–93, which is further stabilized by the contribution of the strongly–interacting bend 77–83. Finally, the rest of the residues come to place.

Summing up, the model suggests that LES are built of residues which lie in the regions 83–93 and 22–34. This essentially agrees with the indirect indications provided by the studies ofMerkel spoke Tuesday with Volodymyr Zelenskiy as election officials said the former TV comedian received 73% of the vote in Sunday's runoff against incumbent Ukrainian President Petro Poroshenko.

Merkel's office said she invited Zelenskiy to visit Germany, while he thanked her for supporting Ukraine and expressed an interest in continuing four-way talks with Russia and France on resolving the conflict in eastern Ukraine.

Merkel's office said Germany will "actively support Ukraine on its path of reform and in its right to sovereignty and territorial integrity."

The statement made no mention of Merkel's recent meeting with Poroshenko — widely seen as supporting his candidacy — before Sunday's vote.
