PhosPhAt

The Arabidopsis Protein Phosphorylation Site Database (PhosPhAt 4.0) contains information on Arabidopsis phosphorylation sites which were identified by mass spectrometry in large scale experiments by different research groups. Specific information about the peptide properties, their annotated biological function as well as the experimental and analytical context is given. For a majority of peptides, the actual annotated mass spectrum is displayed in interactive manner.拟南芥磷酸化位点数据库（Arabidopsis Protein Phosphorylation Site Database, PhosPhAt 4.0）收录了由多个研究团队通过大规模质谱实验鉴定得到的拟南芥磷酸化位点相关信息。该数据库提供了多肽的具体理化性质、注释后的生物学功能，以及实验与分析背景等详细内容。针对大部分多肽，其经过注释的原始质谱图将以交互式界面进行展示。
