title: [Tyrosine tRNA(Q*psiA) from bovine liver. Identification of its sites of interaction with homologous aminoacyl-trna synthetase using chemical modification].
abstract: Interaction of the bovine liver tyrosine tRNA Q*psi A having short variable loop, with the homologous aminoacyl-tRNA synthetase has been studied by alkylation with ethylnitrosourea. It is shown that tyrosyl-tRNA synthetase (form M.r. 2x39000) protects 3'-phosphates of nucleotides 21 in D-loop, 31 and 44 in anticodon stem and 59-64 T psi C-stem of tRNA Tyr from alkylation. An anticodon of tRNA Tyr did not interact with this proteolytically modified form of tyrosyl-tRNA synthetase (M.r. 2x39000).
