TableInfo: ptm.tsv

Detailed information about post-translational modification (PTM) terms

The ptm.tsv table will have as many rows as the number of unique PTM terms appearing in the ptm column of biosample_ptm.tsv and collection_ptm

Field	Field Description	Required?	Field Value Type	Extra Info
id	A unique PTM ID. [Primary key]	Required	string	This ID should be unique across DCCs. One way is to use the MD5 hash value of the concatenated string of the remaining columns (including the optional columns).
protein	A UniProt Knowledgebase (UniProtKB) protein accession (AC)	Required	string (Valid Term)	Example: P14210-1
site_one	Position of the site or first of two positions involved in the site. This would be the first position (start site) for the peptide range.	Required	Positive integers or (empty)	Example: 178
aa_site_one	Amino acid at the first site	Required	Single letter code of AA or (empty)	Example: N
site_two	The second position involved in the site could be of the peptide range (end site) or an alternate position. For the exact position, this will be empty.	Optional	Positive integers or (empty)	Example: 199
aa_site_two	Amino acid at the second site	Optional	Single letter code of AA or (empty)	Example: S
site_type	Type of site, a valid site_type term ID from the CV table site_type.tsv	Optional	String, one of {defined;range;alternative; connect;unknown}	Example: defined. This will be the value in the id column in the row in the CV table site_type.tsv corresponding to the site_type for this PTM, although no formal foreign key constraint is imposed.
ptm_type	Major type of PTM, a valid ptm_type ID	Optional	Gene Ontology ID	Example: GO:0006486. Foreign key: this will be the value in the id column in the row in the table ptm_type.tsv corresponding to the ptm_type for this PTM.
ptm_subtype	Subtype of PTM, a valid ptm_subtype ID	Optional	Gene Ontology ID	Example: GO:0006493. Foreign key: this will be the value in the id column in the row in the table ptm_subtype.tsv corresponding to the ptm_subtype for this PTM.
domain_location	ID for subcellular localization	Optional	Gene Ontology ID	Example: GO:0005634. Foreign key: this will be the value in the id column in the row in the table domain_location.tsv corresponding to the domain_location for this PTM.
domain_type	Domain type	Optional	string	Example: Src homology 3 (SH3) domain
