[Modification of nucleic acids using [3+2] dipolar cycloaddition of azides and alkynes].

The use of the reaction of azide and alkyne cycloaddition for the synthesis of nucleic acid conjugates and DNA oligomer analogues is considered. The data on chemical and enzymatic techniques of azides and alkynes introduction into DNA are summarized.

[Study of the interaction between cytochrome c and cytochrome oxidase by tritium planigraphy]. / Issledovanie vzaimodeistviia tsitokhroma c s tsitokhromoksidazoi metodom tritievoi planigrafii.

Treatment of molecular crystals of the bovine cytochrome oxidase and the cytochrome oxidase-cytochrome c complex with thermally activated tritium leads to highly labelled cytochrome oxidase preparations. HPLC separation of its subunits and measurements of radioactivity of each polypeptide allow to determine the shielding of cytochrome oxidase surface sites by cytochrome c in the complex.
