The A chain is responsible for inhibiting protein synthesis through the catalytic inactivation of 60S ribosomal subunits by removing adenine from position 4,324 of 28S rRNA. Abrin-a is more toxic than ricin., The B chain is a galactose-specific lectin that facilitates the binding of abrin to the cell membrane that precedes endocytosis. Abrin-a Protein, Abrus precatorius, Recombinant (Yeast, His) is expressed in yeast with N-6xHis tag. The predicted molecular weight is 30.1 kDa and the accession number is P11140.
