The chemical components of ribonuclease L (RNase L) from Aspergillus sp. were tested in order to clarify the structure of the enzyme. The molecular weight and the number of the total amino acid residues of the enzyme were about 4.5×104 and 393, respectively. The amino- and carboxyl-terminal amino acids of the enzyme were determined to be glycine and threonine, respectively. RNase L contained about 6% of neutral sugars and an glycopeptide was obtained by digestion with pronase. The isoelectric point of the enzyme was 3.47.
