Table 1 Functions of the Che proteins of Hbt.salinarum

From: The protein interaction network of a taxis signal transduction system in a Halophilic Archaeon

Protein Demonstrated functions in Hbt.salinarum Demonstrated functions of holomogues in other organisms
CheA Phosphorylation of CheY [16] Phosphorylation of CheY and CheB [17, 18]
CheW1   Coupling of CheA to receptors [19]
CheW2   Coupling of CheA to receptors [19]
CheY Essential for switching and Switching/CCW (CW) rotation in Bsu (Eco) [2022]
  CCW swimming [7]  
CheB Receptor demethylation and Receptor demethylation [23, 24]; in Eco also
  deamidation [25] deamidation [26]
CheR Receptor methylation [25] Receptor methylation [23, 27]
CheC1   CheY-P phosphatase [28], CheD inhibition [29, 30]
CheC2   CheY-P phosphatase [28], CheD inhibition [29, 30]
CheC3   CheY-P phosphatase [28], CheD inhibition [29, 30]
CheD   Receptor deamidase and enhancer of CheC in Bsu
   [30, 31], receptor deamidase and methylesterase in
   Tma [32]
CheF1 Coupling Che system to  
  archaeal flagellum [10]  
CheF2   
  1. Functions in other organisms are thought to be universal, unless certain organisms are indicated (Eco: E.coli, Bsu: B.subtilis, Tma: T.maritima).
