Welcome to the Post Translational Modification Structural Database (PTM-SD).

Proteins are composed of a succession of amino acid residues. Their 3D structures are the support of major crucial biological functions.

Post translational modifications (PTMs) are covalent chemical modifications of proteins that typically occur after the protein synthesis.

They allow a fine and sometimes obligatory modulation of biological functions; they can determine proteins activity state, localization, turnover, and interactions with other proteins.

PTM-SD provides an access to proteins for which PTMs are both experimentally annotated and structurally resolved.

We have used different databases to characterize the different PTMs resolved in the protein structures (see HELP page and the FLOWCHART for details on the difficulty to define them properly):

Protein structures are found in Protein Data Bank (http://www.rcsb.org/pdb/home/home.do) [ref]

Sequences contained in PDB were compared with sequences of UniProt database (http://www.uniprot.org/) [ref]

PTMs found in the protein structures were compared with PTMs annotated in dbPTM (http://dbptm.mbc.nctu.edu.tw/) [ref] and PTMCuration (http://selene.princeton.edu/PTMCuration/) [ref]

ANNOTATION FOUND IN MODRES PDB RECORDS

Note:

This filter refers to the annotations found in the MODRES PDB reccords.

ANNOTATION FOUND IN dbPTM

Note:

This filter refers to the experimental sequence annotations taken from dbPTM.

In a limited number of case the selected PTMs of the list could be different from the one observed in the 3D structure. Please check.

	This webserver has been designed by Pierrick Craveur, Joseph Rebehmed and Alexandre G. de Brevern.

	PTM-SD program and the database implementation has been written mainly by Pierrick Craveur, with help of Dr. Joseph Rebehmed.
	Pierrick Craveur had designed the database architecture.
	Dr. Joseph Rebehmed and Dr. Alexandre G. de Brevern conceived the study with Pierrick Craveur.
	All members have extensively tested the database and manually curated the PDB entries.
