GlyTouCan v4 发布：国际聚糖结构数据库重构界面并扩展功能
GlyTouCan v4: a redesigned interface and expanded functionality for the international glycan structure repository
GlyTouCan v4 于 2026 年 6 月 22 日发布，对国际物种中立聚糖结构数据库的界面做了完全重构，浏览与检索速度大幅提升。新版本引入“archetype”视图，把仅在还原端残基异头构型或环形式上不同的登记条目归并展示，便于在已登记的超过 256,000 个聚糖中筛选。结构检索与登记改用更新后的浏览器内嵌 GlycanBuilder，登录方式在 Google 账号之外新增 ORCID ID，v3 REST API 端点保持完全向后兼容。

GlyTouCan (https://glytoucan.org) is the international, species-neutral glycan structure repository that assigns stable, globally unique accession numbers to glycan structures independently of the experimental method used to determine them. Here, we describe GlyTouCan version 4, released on June 22, 2026, which introduces a completely redesigned user interface with substantially faster browsing and searching, including a new “archetype” view that groups registrations that differ only in the anomeric or ring form of the reducing-end residue together for clearer filtering of the >256,000 glycans now registered. Version 4 provides an improved graphical structure input, via the updated browser-embedded GlycanBuilder application, for both searching and registering structures. Users may now sign in with an ORCID ID in addition to a Google account, and all previously released v3 REST API endpoints remain fully backward compatible. Version 4 also introduces a framework for industry affiliates, providing a structured pathway for commercial organizations that work with or synthesize glycans, while all existing academic database-partner relationships are maintained. GlyTouCan remains freely available to all users without charge, login, or registration for browsing and searching. We also summarize the repository’s data content, which spans >600 monosaccharide types and, judging from these, includes many glycans of probable bacterial or plant origin.
