From: Predicting active site residue annotations in the Pfam database
Database entities diagram showing the active site tables (pfamseq_markup and markup_key) in relation to other key tables in the Pfam database. The 'pfamseq' table is one of the central tables in Pfam and contains the sequence information. The Pfam-A alignments (both seed and full) and Pfam-B alignments that a particular active site residue belongs to can be accessed via the tables that link off pfamseq (pfamA_reg_full, pfamA_reg_seed, pfamA, pfamB_reg, pfamB). The red diamonds denote an indexed column and the key symbol denotes the primary key. The diamonds connecting the tables indicate many-to-one relationships with the dark filled end of the diamond indicating the many side of the relationship.
