The best known and studied bacterial toxin is the diphtheria toxin,produced by . Diphtheria toxin is abacterialexotoxin of the A/B prototype. It is produced as single polypeptidechainwith a molecular weight of 60,000 daltons. The function of the proteinis distinguishable into two parts: subunit A, with a m.w. of 21,000daltons,contains the enzymatic activity for inhibition of elongation factor-2involvedin host protein synthesis; subunit B, with a m.w. of 39,000 daltons, isresponsible for binding to the membrane of a susceptible host cell. TheB subunit possesses a region T (translocation) domain which insertsinto the endosome membrane thus securing the release of the enzymaticcomponent into the cytoplasm.

A soy protein-based hydrogel capable of imbibing a large amount of water was synthesized by first modifying the lysyl residues of soy protein isolate (SPI) with ethylenediaminetetraacetic dianhydride (EDTAD) followed by cross-linking with glutaraldehyde. Modification of SPI with EDTAD at pH 9 resulted in polymerization involving intramolecular cross-linking of soy 11S and 7S globulin, which decreased the number of carboxyl moieties introduced per lysyl residue and impaired the swellability of the hydrogel. Pretreatment of SPI involving heating for 30 min at 65 °C and pH 12.0 followed by modification with EDTAD at 25 °C/pH 12 did not result in polymerization and, under these conditions, about 3.3 carboxyl moieties/lysyl residue were incorporated into the protein. The hydrogel prepared under these conditions was able to absorb more than 105 g of water/g of dry gel. The structural changes in SPI caused by the modification and its relevance to swelling properties of the gel are discussed.
