介绍了一个定制的代谢组学NMR数据库TOCCATA,它使用13 C化学位移信息来可靠地识别代谢物、它们的自旋系统和异构体状态。TOCCATA的信息来源于BMRB和HMDB数据库和文献的信息,目前包含463种化合物和801种自旋系统,可以通过http://spinportal.magnet.fsu.edu/toccata/webquery.html上的公开访问网络服务器使用。TOCCATA允许从复杂混合物的13 C-13 C TOCSY实验中鉴定亚mM浓度范围内的代谢物,这在大肠杆菌细胞裂解物、碳水化合物混合物和氨基酸混合物中得到了证明,所有这些都是均匀的13 C标记的。
A customized metabolomics NMR database, TOCCATA, is introduced, which uses 13C chemical shift information for the reliable identification of metabolites, their spin systems and isomeric states. TOCCATA, whose information was derived from information of the BMRB and HMDB databases and the literature, currently contains 463 compounds and 801 spin systems and it can be used through a publicly accessible web server at http://spinportal.magnet.fsu.edu/toccata/webquery.html. TOCCATA allows the identification of metabolites in the sub-mM concentration range from 13C-13C TOCSY experiments of complex mixtures, which is demonstrated for an E.coli cell lysate, a carbohydrate mixture, and an amino acid mixture, all of which were uniformly 13C-labeled.
