PTM / Processing section

Last modified October 30, 2015

This section describes post-translational modifications (PTMs) and/or processing events.

The information is filed in different subsections. The current subsections and their content are listed below:

Subsection Content
Initiator methionine Cleaved initiator methionine
Signal Sequence targeting proteins to the secretory pathway or periplasmic space
Propeptide Part of a protein that is cleaved during maturation or activation
Transit peptide Extent of a transit peptide for organelle targeting
Chain Extent of a polypeptide chain in the mature protein
Peptide Extent of an active peptide in the mature protein
Modified residue Modified residues excluding lipids, glycans and protein crosslinks
Lipidation Covalently attached lipid group(s)
Glycosylation Covalently attached glycan group(s)
Disulfide bond Cysteine residues participating in disulfide bonds
Cross-link Residues participating in covalent linkage(s) between proteins
Post-translational modification Description of post-translational modifications
Keywords ‘PTM’ Selection of controlled vocabulary which summarises the content of an entry
Proteomics and PTM databases Selection of cross-references that point to data collections other than UniProtKB
