Protein Feature Data

Attributes

• aa_sequence_md5 (string) - 32-character digest used for rapid duplicate detection and cross-genome joins without transmitting the entire sequence. "0cc175b9c0f1b6a831c399e269772661"
• classification (array of strings) - Curated labels such as domain, family, motif, signal_peptide, transmembrane that drive colour-coding in viewers and filter facets. [ "domain", "TIM_barrel" ]
• comments (array of case insensitive strings) - Free-text remarks (e.g. “borderline hit”, “possible frameshift”) kept as an array so each note is distinct. [ "low complexity region extends into hit" ]
• date_inserted (date) - ISO-8601 UTC datetime when the row entered BV-BRC; used by incremental exporters. "2023-05-12T14:22:09Z"
• date_modified (date) - Updated whenever any value changes, allowing cache refresh. "2025-04-29T08:11:55Z"
• description (case insensitive string) - Human-readable title of the matched domain/family (e.g. “Peptidase S8, domain A”). "Peptidase S8 family"
• e_value (string) - Scientific notation string from HMMER/BLAST alignment indicating statistical significance. "3.4e-45"
• end (integer) - 1-based inclusive amino-acid coordinate where the feature stops on the protein. 275
• evidence (string) - Short code or phrase such as HMM, BLAST, Curated, Experiment. Guides confidence displays. "HMM"
• feature_id (string) - Stable `fig …` identifier of the CDS that encodes this protein.
• feature_type (string) - Usually CDS; future-proof for peptides translated from RNAs or frameshifts. "CDS"
• gene (string) - Short locus name derived from annotation or GenBank. "subA"
• genome_id (string) - BV-BRC genome_id linking to genome metadata. "511145.183"
• genome_name (case insensitive string) - De-normalised for quick table display. "Escherichia coli K-12 MG1655"
• id * (string) - Unique row key `feature_id
• interpro_description (case insensitive string) - High-level description that unifies Pfam/SMART/CDD hits; blank if no InterPro mapping. "Peptidase S8/S53 domain"
• interpro_id (string) - InterPro identifier (IPRxxxxxx) harmonising multiple domain DBs. "IPR000209"
• length (integer) - Number of residues covered by the domain/motif. 218
• patric_id (string) - Retained for legacy APIs; identical to feature_id for CDS. `"fig
• product (case insensitive string) - Functional description copied from CDS annotation for context. "Subtilisin-like serine protease"
• publication (array of strings) - PubMed IDs or DOIs linked to experimental validation of the domain’s function. [ "PMID:23456789" ]
• refseq_locus_tag (string) - Official NCBI tag for cross-referencing GenBank/RefSeq records. "ECOLI_RS10330"
• score (number) - Bit score or log-odds score returned by HMM search. 187.4
• segments (array of strings) - For split or discontinuous domains: array of "start..end" strings. [ "58..125", "190..275" ]
• sequence (string) - Exact AA sequence spanned by the domain/motif; blank if withheld for size. "DILGIGLE…ALGT"
• source (string) - PFAM, SMART, CDD, TIGRFAM, SignalP, etc. "PFAM"
• source_id (string) - Identifier of the hit within source (e.g. PF00082). "PF00082"
• start (integer) - 1-based inclusive coordinate where the feature starts on the protein. 58
• taxon_id (integer) - Taxon of the parent genome; enables taxon-scoped domain frequency analysis. 562
