[A spectrophotometric study of Penicillium brevicompactum RNAase complex formation with adenine nucleotides].

Spectrophotometric study of extracellular Pen. brevicompactum RNAse interaction with adenyl nucleotides and constituents have been carried out. It is states that: 1) complex RNAse--nucleotide is formed by association of one enzyme molecule with one nucleotide molecule; 2) all the nucleotide components base sugar and phosphate, take part in the formation of this complex; 3) for the effective association of this complex it is necessary to have a high correspondence (complementaryty) of nucleotide geometric configuration to the space composition of the active site of RNAse.
