Two-component systems, rebuilt for exploration

Protein BLAST

Search a protein sequence against HK or RR cluster databases.

Choose MMseq2, blastp, or DIAMOND in the interface, then search either the HK or RR cluster database. MMseq2 remains the fastest default for interactive use, while blastp now defaults to blastp-fast with 4 threads.

Protein sequence search

Single-sequence query against prebuilt HK and RR search databases

Expert parameters mode

Leave a field empty to keep the engine default values.

`mmseq2`, `blastp`, and `DIAMOND` each use their own local database build. The HK and RR cluster FASTA files therefore need to be indexed before the first search.
