脆弱拟杆菌是人类肠道微生物组的丰富组成部分,可能利用细胞表面和分泌的分子定植宿主并与其他微生物相互作用。虽然许多外膜蛋白可以通过生物信息学方法从基因组序列中预测,但这些蛋白在不同条件下的表达尚未得到检验。此外,具有不寻常特征的外膜蛋白和由新机制分泌的蛋白质无法通过硅方法识别。为了解决这些问题,我们目前正在使用多维蛋白鉴定技术(MudPIT)和其他基于质谱的方法分析脆弱芽孢杆菌的外膜蛋白质组和分泌组。
英文摘要
Bacteroides fragilis is an abundant constituent of the human gut microbiome that presumably uses cell surface and secreted molecules to colonize the host and interact with other microorganisms. Although many outer membrane proteins can be predicted from the genome sequence by bioinformatic methods, the expression of these proteins under different conditions has not been examined. Furthermore, outer membrane proteins that have unusual features and proteins that are secreted by novel mechanisms cannot be identified by in silico methods. To address these issues, we are currently analyzing the outer membrane proteome and secretome of B. fragilis using multidimensional protein identification technology (MudPIT) and other mass spectrometry-based methods.
