Substitution of histidine-137 by glutamine abolishes the catalytic activity of the ribosome-inactivating protein alpha-sarcin.
The alpha-sarcin cytotoxin is an extracellular fungal protein that inhibits protein biosynthesis by specifically cleaving one phosphodiester bond of the 28 S rRNA. The His137 residue of alpha-sarcin is suggested to be involved in the catalytic activity of this protein, based on the observed sequence...
