Multiple forms of acetylcholinesterase from pig brain.
1. A number of methods of solubilization of pig brain acetylcholinesterase (EC 3.1.1.7) were studied. The multiple enzymic forms of the resultant preparations were examined by polyacrylamide-gel electrophoresis. 2. Butanol extraction, Nagarase treatment and ultrasonication proved unsuitable as preparatory methods, but detergent treatment (Triton X-100, Triton X-100-KCl and lysolecithin) gave go...
متن کاملCa2%-binding protein from pig duodenum
The cation-binding properties of the vitamin D-dependent Ca2 +-binding protein from pig duodenum were investigated, mainly by flow dialysis. The protein bound two Ca2 + ions with high affinity, and Mg2 +, Mn2+ and K+ were all bound competitively with Ca2 + at both sites. The sites were distinguished by their different affinities for Mn2 +, the one with the higher affinity being designated A (Kd...
متن کاملMultiple forms of membrane-bound beta-glucosidase in human leucocytes.
insulin has been suggested by Cuatrecasas & Illiano (197 1) on the basis of neuraminidase treatment of adipose-tissue cells. Enzymic digestion was reported to have no effect on the total quantity of insulin receptor in the membranes or on the affinity of the receptor for insulin, but abolished the effect of insulin on glucose transport and on lipolysis. As shown in Fig. 1, neuraminidase action ...
متن کاملAlpha glucosidase inhibitors.
Alpha glucosidase inhibitors (AGIs) are a unique class of anti-diabetic drugs. Derived from bacteria, these oral drugs are enzyme inhibitors which do not have a pancreato -centred mechanism of action. Working to delay carbohydrate absorption in the gastrointestinal tract, they control postprandial hyperglycaemia and provide unquestioned cardiovascular benefit. Specially suited for a traditional...
متن کاملPeptide modulators of alpha-glucosidase
AIMS/INTRODUCTION Acute glucose fluctuations during the postprandial period pose great risk for cardiovascular complications and thus represent an important therapeutic approach in type 2 diabetes. In the present study, screening of peptide libraries was used to select peptides with an affinity towards mammalian intestinal alpha-glucosidase as potential leads in antidiabetic agent development. ...
