  • Title: Optimum pH control mechanism for porcine pancreatic alpha-amylase.
    Author: Ishikawa K, Matsui I, Honda K.
    Journal: Biosci Biotechnol Biochem; 1995 Jun; 59(6):1175-6. PubMed ID: 7613011.
    Abstract:
    We studied the substrate-dependence of pH activity of porcine pancreatic alpha-amylase by using a series of p-nitrophenyl maltooligosaccharides. The mechanism controlling the optimum pH of mammalian alpha-amylase involved the reception and recognition of a substrate component at some other substrate binding sites, in addition to those at subsite 5 that were reported previously [K. Ishikawa et al., Biochemistry, 32, 6259-6265 (1993)].
