RCSB PDB Sequence Coordinates API

GraphQL service providing sequence-level alignments between structural databases and external sequence resources. Exposes two core queries — alignment and annotations — enabling callers to map PDB chain positions to UniProt, NCBI RefSeq (protein and genomic), CATH, SCOPe, and Computed Structure Models (CSMs). Replaces the legacy 1D Coordinates Service.
