Methods for the pasteurella glycosaminoglycan synthases: Enzymes that polymerize hyaluronan, chondroitin, or heparosan chains

Abstract

Multiple glycosyltransferases (GTases) that produce glycosaminoglycans (GAGs) have been identified; Â?several distinct putative architectures and catalytic abilities have been noted from microbes and vertebrates. Here the preparation and use of a class of enzymes (Class II) from the gram-negative bacterium, Pasteurella multocida, with utility in chemoenzymatic synthesis of GAGs is described. The analyses of sugar products include thin layer chromatography (TLC), matrix-assisted laser desorption ionization mass spectroscopy (MALDI-ToF MS), and polyacrylamide gel electrophoresis (PAGE). The related Chapter 18 is focused on larger molecular weight GAGs analyses as well as the Class I membrane streptococcal and mammalian HA synthases. © Springer Science+Business Media New York 2013.
