• Talaromyces emersoni xylanase

  Talaromyces emersonii secretes between 14-20 distinct endoxylanase components when grown on the appropriate carbon source. Thirteen of these endoxylanases have been purified to homogeneity and characterized with respect to catalytic properties. The molecular weights of the purified endoxylanases vary between 30-130 kDa. Xylanase and glucanase expression is not equivalent between 10 Talaromyces emersonii strains grown under identical conditions on the same nutrient medium and carbon inducers. A new low molecular weight xylanase has been identified, Xyn XII (17.5 kDa) from the xylan-degrading system of the T. emersonii IMI393751 strain. The temperature optimum for Xyn XII-catalyzed degradation of the arabinoxylan OSX was determined to be 75 °C, and the optimum pH for activity was pH 4.0 - 4.5. Xyn XII was remarkably acid stable and retained over 91 % of its original activity at pH 3.0. Xyn XII is most active on a mixed-linkage, unsubstituted D-xylan. It displayed substantial activity against mixed-linkage D-glucans, and it displayed activity against aryl-β-xylosides. In vivo, Xyn XII may play a very important role for T. emersonii IMI393751 in providing access to plant cell wall hemicellulose.

  当 Talaromyces emersonii 在适当的碳源上生长时，会分泌 14-20 种不同的内切酶成分。其中 13 种内聚糖酶已被纯化至均一，并具有催化特性。纯化的内切酶分子量在 30-130 kDa 之间。在相同的营养培养基和碳诱导剂条件下生长的 10 株塔拉酵母（Talaromyces emersonii）之间，木聚糖酶和葡聚糖酶的表达量并不相同。从 T. emersonii IMI393751 菌株的木聚糖降解系统中发现了一种新的低分子量木聚糖酶 Xyn XII（17.5 kDa）。经测定，Xyn XII 催化降解阿拉伯木聚糖 OSX 的最佳温度为 75 °C，活性的最佳 pH 值为 pH 4.0 - 4.5。Xyn XII 具有显著的酸稳定性，在 pH 值为 3.0 时仍能保持超过 91% 的原始活性。 Xyn XII 对混合连接的未取代 D-木聚糖活性最强。它对混合连接的 D-葡聚糖有很强的活性，对芳基-β-木糖苷也有活性。在体内，Xyn XII 可能对 T. emersonii IMI393751 进入植物细胞壁半纤维素起着非常重要的作用。
