Fig 1. A schematic diagram of a monomer subunit of TSK showing a sensor domain, an HK domain, a receiver domain, and an HPt domain.

Fig 1

The HK domain contains two subdomains: a DHp subdomain and a CA subdomain. The N, G1, F, and G2 boxes are conserved sequence motifs in histidine sensor kinases.
