真核生物聚糖的长触角是由聚乳糖胺重复序列构成的。聚乳糖胺形成凝集素识别位点并且还充当用于呈现多种额外修饰的平台(例如,末端细胞表面抗原);因此,它在细胞粘附、发育和免疫中起重要作用。两篇新论文详细研究了触角合成中的关键酶β1-3-N-乙酰葡糖胺转移酶2的结构和机制。由此产生的见解也将有助于破译GT31的其他成员,GT31是人类最大的糖基转移酶家族。
The elongated antennae decorating eukaryotic glycans are built from polylactosamine repeats. Polylactosamine forms a lectin recognition site and also acts as a platform for presenting diverse additional modifications (e.g., terminal cell-surface antigens); it therefore plays important roles in cell adherence, development, and immunity. Two new papers present a detailed structural and mechanistic investigation of β1-3-N-acetylgucosaminyltransferase 2, a key enzyme in antennae synthesis. The resulting insights will also help decipher other members of GT31, the single largest human glycosyltransferase family.
