摘要: Background: His-Asp phosphorelay proteins can be components of complex signaling systems. Results: Two hybrid histidine kinases, EspA and EspC, form a complex; phosphorylates both receiver modules to regulate proteolytic turnover regulatory protein. Conclusion: kinases are integrated by inter- intra-histidine aspartate phosphotransfer. Significance: A novel signal transduction mechanism was identified.
