␣-Sarcin is a ribotoxin secreted by the mold Aspergillus giganteus that degrades the ribosomal RNA by acting as a cyclizing ribonuclease. Three residues potentially involved in the mechanism of catalysis-histidine-50, glutamic acid-96, and histidine-137-were changed to glutamine. Three different sin
