[RNAse substrate specificity in Acholeplasma laidlawii PG-8].

A substrate specificity of RNAses of A. laidlawii PG-8 to polynucleotides - poly (C), poly (U), poly (A) has been studied. Due to the data obtained both intracellular and extracellular RNAses of A. laidlawii possess similar specificity to different polynucleotides. Both RNAses preferentially break cytidine-bonds. Specificity of the studied enzymes in respect to polyuridylic and polyadenylic acids was less expressed.
