Abrin is one of the potent toxins isolated from the beans of plant abrus precatorius.the toxic protein consists of two disulfide-bonded subunits,the a and b chains.the b chain is a galactose-specific lectin that facilitates the binding of abrin to the cell membrane that precedes endocytosis.after entering the cells,the a chain catalytically inactivates 60s ribosomal subunits by removing adenine position 4324 of 28s r–rna,and thereby inhibits protein biosynthesis.
