Follow the protein-reagent siblings Bovine_Serum_Albumin and Lysozyme: identifier is the enzyme's CAS 9001-05-2 (EC 1.11.1.6), broadMatch to the species-neutral MeSH descriptor mesh:D002374 'Catalase', Rule B1 registry row.

2026-06-10T06:49:42.119337+00:00	fix_dead_chebi_ids.py	CORRECTED		identifier CHEBI:3463 -> NCIT:C61062 (Catalase, source NCIT): CHEBI:3463 is absent from current ChEBI (OLS4 404).
2026-08-27T03:16:39.518532+00:00	refresh_occurrence_statistics	CORRECTED		occurrence_statistics 26/26 -> 34/34 (media_count/total_occurrences), derived from distinct CultureMech recipe ids in the #337 occurrence table. The prior values came from the importer retired in #453, whose media_count counted a list truncated to 50 examples (#449).

2026-08-30T04:48:06.233536+00:00	claude_culturemech_alias_backfill	ADDED_SYNONYMS		Added 1 CultureMech recipe surface form(s) that folded onto this record's published label but were absent from MIM's label index, so CultureMech could not resolve them: 'Catalase (Sigma C--10)' (x1 CultureMech mentions).
