Our results showed that Wa1F1-KT shares at least one epitope with the KT produced by W. anomalus ATCC 96603, although the molecular mass of the two toxins is slightly different, indicating that they are related but not identical. Both Wa96603-KT and Wa1F1-KT degraded the soluble β-glucan laminarin in a manner similar to laminarinase, an endo-1,3(4)-β-glucanase, as did Wm41968-KT, whose glucanase activity had been already suggested .
