Data Type: feature_sequence

Primary Key: md5

_version_ (number)
date_inserted (date) - ISO-8601 UTC datetime when the sequence row entered BV-BRC. Used by ETL jobs and incremental export utilities. "2023-07-14T11:22:31Z"
date_modified (date) - Updated whenever any field in the row changes (e.g. sequence correction). Lets clients refresh only modified records. "2025-04-29T08:17:45Z"
md5 * (string) - 32-character hexadecimal MD5 digest of the raw sequence characters (uppercase FASTA, no gaps). Serves as the primary key, allowing rapid deduplication and cross-genome look-ups. "0cc175b9c0f1b6a831c399e269772661"
sequence () - Full FASTA content (without header) for the feature: DNA for genes/RNAs, protein for CDS translations. Stored in compressed blocks; streamed on demand for downloads and BLAST queries. "ATGAC…TAA" (DNA) / "MQTLV…KQL" (protein)
sequence_type (string) - Indicates whether sequence is dna, rna, or protein. Guides downstream tools to choose translation, alignment, or motif settings correctly. "protein"
