[The existence of the ribonucleoprotein branching enzyme in rabbit skeletal muscle and ribozyme corresponding to it].

Amylose isomerase (AI) preparations were isolated from rabbit muscles after Petrova et al., as well as by the additional fractionation steps. Their homogeneity, enzymatic activity and RNA, isolated from those preparations, were characterized.

[Interaction of s4U8 region of tRNA Phe with tRNA-(adenine-1-)-methyltransferase from Thermus thermophilus].

Photoaffinity labelling of tRNA (adenine-1-)-methyltransferase with an E. coli tRNA(Phe) derivative bearing 4-azidophenylmercuro group attached to s4U residue as well as direct photocross-linking of the native tRNA(Phe) with the enzyme via s4U residue has been studied. Both techniques labelling gave similar results, leading to covalent attachment of tRNA(Phe) to the enzyme within a specific complex.
