SysPTM Version 2.0, updated June 15th, 2013.   Visits:  110.

SysPTM provides a systematic and sophisticated platform for proteomic PTM research, equipped not only with a knowledge base of manually curated multi-type modification data, but also with four fully developed, in-depth data mining tools. Currently, SysPTM contains data detailing 471109 experimentally determined PTM sites on 53235 proteins, covering more than 50 modification types, curated from public resources including five databases and four webservers and more than three hundred peer-reviewed mass spectrometry papers. Protein annotations including Pfam domains, KEGG pathways, GO functional classification, and ortholog groups are integrated into the database. Five online tools have been developed and incorporated, including: PTMBlast, PTMPathway, PTMPhylog, PTMCluster and PTMGO.In SysPTM, the roles of single-type and multi-type modifications can be systematically investigated in a full biological context. SysPTM could be an important contribution to modificomics research.
