title: [Use of rare earth elements as markers for the study of biologically active compounds. V. Luminescence spectra and binding centers of europium in proteins].
abstract: Luminescence spectra of europium ions bound to some proteins are investigated. Europium is shown to coordinate no more than two charged groups, first of all carboxyles. The possibility of more specific coordination of rare earths in proteins is discussed.
