P2CS-Web
Two-component systems, rebuilt for exploration
Search annex data
Dedicated search channels for external mappings and future annex datasets.
This entry point is separate from genome, gene, and cluster search so we can add annex-specific searches without overloading the core catalog forms.
External mappings
RefSeq, UniProt, GO, and PubMed links resolved from p2cs_annexes.db
Use this channel to search identifiers and literature-oriented annotations, then jump back to linked P2CS genes and clusters when a mapping exists.
Future annex searches
Reserved for upcoming datasets
Additional annex channels can be added here later without changing the global `Search` menu again.
