Phosphorelays
WebThe general properties of phosphorelay architectures are relatively unexplored and it remains a mystery why some signaling systems make use of single-step phosphotransfers and others phosphorelays. One possibility is that the intermediate steps in phosphorelays provide additional points of control. WebIn general, TCs are located at strategically important positions for nutrient acquisition and exchange, such as symplasmic/apoplasmic interfaces in vascular tissues and seeds, reproductive and secretory organs and at contact points of plant/symbiotic and plant/parasitic interactions.
Phosphorelays
Did you know?
In orthodox two-component signaling, a histidine kinase protein autophosphorylates on a histidine residue in response to an extracellular signal, and the phosphoryl group is subsequently transferred to an aspartate residue on the receiver domain of a response regulator. In phosphorelays, the "hybrid" histidine kinase contains an internal aspartate-containing receiver domain to which the phosphoryl group is transferred, after which an HPt protein containing a ph… WebNov 7, 2013 · Phosphorelays are extended two-component signaling systems, which embed additional proteins (or domains) between a HK and RR pair. As such they are the result of evolution exploiting the highly modular nature of two-component proteins . Here, we …
WebOne type of these signal transduction systems are the so-called Two Component Systems (TCS), which conduct the transfer of phosphate groups between specific and conserved histidine and aspartate residues present in at least two proteins; the first protein is a sensor kinase which autophosphorylates a histidine residue in response to a stimulus, … WebNov 1, 2007 · His-Asp phosphorelays are widespread signal transduction mechanisms in bacteria, fungi, and higher plants.
