Template:STRUCTURE 1kgs

Response regulators (RR) are part of the two-component signal transduction systems which enable bacteria to sense and respond to a wide range of environments. Two-component RR is a complex of histidine kinase (sensor protein SP) and RR. The RR act as phosphorylation-activated switches. Most RR consist of N terminal shich is the signal receiving domain and C terminal which is the DNA-binding domain. RR CheY is a chemotaxis response regulator in bacteria. RR Spo0 is the sporulation response regulator. For details see:
For PleD:

• PleD activation
  
• PleD allosteric product inhibition
  
• PleD catalysis
  
• Response regulator PLED in complex with C-di-GMP
  

For PhoP:

• PhoP Regulatory Domain
  
• PhoP-PhoQ
  

For photosynthetic apparatus RR:

• PrrA in Rhodobacter sphaeroides
  

For WspR RR:

• WspR.
