dbPTM

Latest news:

Jan. 20, 2008:
The structural information, protein disorder regions, will be annotated on dbPTM in Feb. 2008!

Four external biological databases related to protein post-translational modification information, Swiss-Prot, Phospho.ELM, O-GLYCBASE, and UbiProt, are integrated into the proposed resource, as shown in statistics page. Furthermore, the experimentally validated sites in each type of PTM were categorized by the modified amino acid, and the number of experimentally validated sites is provided in the summary table, as shown in bellow. Users can investigate into the substrate peptide specificity of each categorized PTM.

PTM Type	Ala(A)	Arg(R)	Asn(N)	Asp(D)	Cys(C)	Gly(G)	Glu(E)	Gln(Q)	His(H)	Ile(I)	Leu(L)	Lys(K)	Met(M)	Phe(F)	Pro(P)	Ser(S)	Thr(T)	Trp(W)	Tyr(Y)	Val(V)
