图2 木聚糖生物合成示意图(参考Qaseem and Wu, 2020) UGD: UDP-葡萄糖脱氢酶; UXS: UDP-木糖合成酶; UAM: UDP-阿拉伯糖变位酶; UUAT1: UDP-糖醛酸转运蛋白; UXT: UDP-木糖转运蛋白; UAfT: UDP-阿拉伯糖转运蛋白; UXE: UDP-木糖差向异构酶。虚线箭头表示转运过程, 实线箭头表示化学反应过程, 问号表示未知。

Figure 2 Schematic diagram of xylan biosynthesis (refer to Qaseem and Wu, 2020) UGD: UDP-Glc dehydrogenase; UXS: UDP-Xyl synthase; UAM: UDP-Ara mutase; UUAT1: UDP-Uronic acid transporter 1; UXT: UDP-Xyl transporter; UAfT: UDP-Araf transporter; UXE: UDP-Xyl epimerase. Dotted arrows show the transport process, the solid arrows show the chemical reaction process, question mark indicates unknown.
