Abstract excerpt

Radiationless energy transfer from tyrosine to Tb(III) in Escherichia coli glutamine synthetase and its two mutants (W57L and W158S) has been utilized to assess the tyrosine residue(s) responsible for the observed tyrosine emission and to investigate its spatial relationships to the two metal bin...
