NCBI E-utilities for biological sequences — fetch protein/nucleotide FASTA by accession, run BLAST, translate CDS to protein, search NCBI Protein by gene+organism. Use when the user provides an NCBI accession (NP_, XP_, NM_, NR_, etc.), asks for a sequence by gene name + species, or needs to translate a coding sequence. Don't use for ClinVar variants (use ncbi_clinvar) or gene metadata lookup (use ncbi_gene).
