A Transglucosylase of Streptococcus Bovis.
1. A transglucosylase has been separated from the alpha-amylase of Streptococcus bovis by chromatography of the cell extract on DEAE-cellulose. 2. The transglucosylase can synthesize higher maltodextrins from maltotriose, but maltose, isomaltose and panose do not function as donors. 3. Iodine-staining polysaccharide may be synthesized from maltotriose provided that glucose is removed. Synthesis...
متن کاملPurification and Characterization of Extracellular, Polyextremophilic α-amylase Obtained from Halophilic Engyodontium album
Background: a-Amylases (EC 3.2.1.1) are covering approximately 25% of total enzyme market and are frequently used in food, pharmaceutical and detergent industries. Objectives: The first ever detailed characterization of amylase from any halophilic Engyodontium album is presented. Materials and Methods: An extracellular α-amylase was studied from halophilic E. album TISTR 3645. The enzyme was e...

متن کاملInhibitory Effects of Swietenia Mahagoni Seeds Extract on Α-Glucosidase and Α-amylase
This study analyzed the inhibition activity of Swietenia mahagoni seeds extract on α-glucosidase and α-amylase enzymes inhibition assays. Swietenia mahagoni seeds were extracted by using Supercritical Carbon Dioxide (SC-CO2) extraction at pressures of 20- 30 MPa and temperatures of 40- 60°C. The oil yields obtained were analyzed with α- glucosidase and α- amylase enzymes inhibition assays. A...
متن کاملPurification and Characterization of the Extracellular a-Amylase from Streptococcus bovis JBl
The extracellular a-amylase (1,4-a-D-glucanglucanohydrolase; EC 3.2.1.1) from maltose-grown Streptococcus bovis JBl was purified to apparent homogeneity by ion-exchange chromatography (Mono Q). The enzyme had an isoelectric point of 4.50 and an apparent molecular mass of 77,000 Da, as estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The enzyme was rich in acidic and hydro...
