Abstract: Glycogen branching enzymes (GBEs; 1,4-α-glucan branching enzyme; E.C. 2.4.1.18) have so far been described to be capable of both α-1,6-transglycosylation (branching) and α-1,4-hydrolytic activity. The aim of the present study was to elucidate the mode… read more here.

Abstract: Glycogen-like particles (GLPs) were built up from sucrose by applying de novo one-pot enzymatic process of amylosucrase (ASase; 6 U·mL-1) and glycogen branching enzymes (GBEs; 0.001 and 0.005 U·mL-1). Due to different chain-length transferring patterns of GBEs,… read more here.

DOI: 10.1080/07388551.2020.1713720
Abstract: Abstract The 1,4-α-glucan branching enzymes (GBEs) are ubiquitously distributed in animals, microorganisms and plants. These enzymes modify the structure of both starch and glycogen; changing the frequency and position of branches by forming new α-1,6-glucosidic… read more here.
