GlyMDB
收藏资源简介:
GlyMDB links microarray data to PDB structures. It provides different options for database query, and allows users to upload their microarray data for analysis. After search or upload is complete, users can choose the criterion for binder versus non-binder classification. Users can view the signal intensity graph including the binder/non-binder threshold followed by a list of glycan-binding motifs. One can also compare the fluorescence intensity data from two different microarray samples. A protein sequence-based search is performed using BLAST to match microarray data with all available PDB structures containing glycans. The glycan ligand information is displayed, and links are provided for structural visualization and redirection to other modules in GlycanStructure
GlyMDB可将微阵列数据与PDB(Protein Data Bank,蛋白质数据库)结构进行关联。该数据库提供多元化的数据库查询方案,支持用户上传自身的微阵列数据以开展分析。完成搜索或数据上传操作后,用户可自主选定用于区分结合物与非结合物的分类标准。用户可查看包含结合物/非结合物阈值的信号强度图谱以及聚糖结合基序列表。此外,用户还可对两份不同微阵列样本的荧光强度数据开展比对分析。系统采用BLAST(Basic Local Alignment Search Tool,基本局部比对搜索工具)执行基于蛋白质序列的搜索,将微阵列数据与所有已收录的含聚糖PDB结构进行匹配。系统将展示聚糖配体相关信息,并提供结构可视化链接以及跳转至GlycanStructure中其他模块的入口。
