The protmod module contains an XML file, defining a list of protein modifications, retrieved from Protein Data Bank Chemical Component Dictionary, RESID, and PSI-MOD. It contains many common modifications such glycosylation, phosphorylation, acelytation, methylation, etc. Crosslinks are also included, such disulfide bonds and iso-peptide bonds.
The protmod maintains a registry of supported protein modifications. The list of protein modifications contained in the XML file will be automatically loaded. You can define and register a new protein modification if it has not been defined in the XML file. From the protein modification registry, a user can retrieve:
- all protein modifications,
- a protein modification by ID,
- a set of protein modifications by RESID ID,
- a set of protein modifications by PSI-MOD ID,
- a set of protein modifications by PDBCC ID,
- a set of protein modifications by category (attachment, modified residue, crosslink1, crosslink2, …, crosslink7),
- a set of protein modifications by occurrence type (natural or hypothetical),
- a set of protein modifications by a keyword (glycoprotein, phosphoprotein, sulfoprotein, …),
- a set of protein modifications by involved components.
// a protein modification by ID
ProteinModification mod = ProteinModificationRegistry.getById(“0001”);
Set mods;
// all protein modifications
mods = ProteinModificationRegistry.allModifications();
// a set of protein modifications by RESID ID
mods = ProteinModificationRegistry.getByResidId(“AA0151”);
// a set of protein modifications by PSI-MOD ID
mods = ProteinModificationRegistry.getByPsimodId(“MOD:00305”);
// a set of protein modifications by PDBCC ID
mods = ProteinModificationRegistry.getByPdbccId(“SEP”);
// a set of protein modifications by category
mods = ProteinModificationRegistry.getByCategory(ModificationCategory.ATTACHMENT);
// a set of protein modifications by occurrence type
mods = ProteinModificationRegistry.getByOccurrenceType(ModificationOccurrenceType.NATURAL);
// a set of protein modifications by a keyword
mods = ProteinModificationRegistry.getByKeyword(“phosphoprotein”);
// a set of protein modifications by involved components.
mods = ProteinModificationRegistry.getByComponent(Component.of(“FAD”));
