Protein
Ribonuclease clavin
Organism
Aspergillus clavatus (strain ATCC 1007 / CBS 513.65 / DSM 816 / NCTC 3887 / NRRL 1)
Function
Clavin has the same substrate specificity as alpha-sarcin. It is specific for purines in both single- and double-stranded RNA. Its toxic action on eukaryotic cells is the result of cleavage of a single phosphodiester bond in the 60S subunit of ribosomes.
Similarity
Belongs to the ribonuclease U2 family.
