Bacteria produce a remarkable range of surface and secreted polysaccharides. Two pathways have been defined for the biosynthesis and export of capsular polysaccharides and exopolysaccharides in Gram-negative bacteria. A structure of AlgK described in this issue provides structural insight into a third previously unrecognized pathway associated with important biopolymers (Keiski et al., 2010).
细菌产生了广泛的表面和分泌多糖。革兰氏阴性菌中已确定了两种途径来合成和导出荚膜多糖和胞外多糖。本期中描述的 AlgK 结构提供了对与重要生物聚合物相关的第三个以前未被识别的途径的结构见解（Keiski 等人，2010 年）。
