| additional information | determination of xylanase activity by measuring the release of reducing sugars from oat-spelt xylan, production of xylobiose, xylotriose and xylotetrose by a crude enzyme extract. The purified recombinant His-tagged acetylxylan esterase has broad substrate specificity for various carboxyl esters. Among the polyoxyethylenesorbate esters tested, the enzyme has the highest activity for polyoxyethylenesorbate monolaurate, but moderate or little activity for longer acyl chains. The enzyme is able to hydrolyze both acetylxylan and acetylcellulose, but acetylxylan has a better hydrolytic rate | Thermobifida fusca | ? | - |
