productsTo confirm the identity of AmyASS, it is necessary to exam-ine the range of substrate hydrolysis and the product profile ofAmyASS. Apart from soluble starch (44.6 ± 2.8 U mg−1, relativeactivity 100%), the enzyme only cleaved amylose (38 ± 0.8%). Noactivity could be determined with amylopectin, pullulan and glyco-gen as the substrates.
