Cloning and functional comparison of a high-affinity K + transporter …

WebThe K + channel was now characterized by a high-affinity component of K m = 0.2mM and a low-affinity component of K m = 7.3mM ( Figure 1B ), while the K + /H + co-transporter had a high-affinity component of K m = 0.01mM and a low-affinity component of K m = 2.3mM ( Figure 1D ). FIGURE 1 Figure 1 The pitfalls of affinity analyses. Weba high-affinity K+ transporter PhaHKTI were isolated from salt-sensitive (Utsunomiya) and salt-tolerant (Nanpi, Enchi) reed plants. A cDNA of Utsunomiya (PhaHKT1-u) contained two insertions in the region corresponding to the first and second introns of the PhaHKTI gene, which resulted in a sequence 141 amino acid residues shorter than that of ... csc mc on undertime

Identification and characterization of HAK/KUP/KT potassium transporter …

High Affinity K + transporter HAK5, is important for the regulation of K + ions within the cell. When there is a lack of K +, the HAK5 transporter is activated to uptake K +. This occurs when there is high salinity within the soil, which often happens within the crop industry. Ver mais High Affinity K transporter HAK5 is a transport protein found on the cell surface membrane of plants under conditions of potassium deprivation. It is believed to act as a symporter for protons and the potassium ion, K . Firstly … Ver mais The High Affinity K transporter interacts with the following proteins • ILK1 • CBL9- CIPK23 Ver mais High Affinity K transporter HAK5 effects multiple functions of the plant when in low potassium concentrations these are; • Ver mais CIPK23 acts to phosphorylate HAK5, the phosphorylation is what activates the HAK5 to take up K . HAK5 is positively controlled by CIPK23- CBL1-9 complexes, Ca binds with CBL1-9, which then combines with CIPK23 to form a CIPK23/CBL … Ver mais • Pubmed • IHOP • Uniprot: maize, rice • Wikigenes Ver mais Web14 de ago. de 1998 · 1 Introduction. HKT1 is expressed in the roots of Triticum aestivum and encodes a high affinity K + symport that is energized by Na + [1-3].Na + energized K + uptake mechanisms have been characterized in lower plants such as the fresh water charophyte alga, Chara corallina [].HKT1 is the first Na + energized transporter to be … WebIn this study, the role of AtHAK5 in high affinity K + and Cs + uptake was characterized. It is demonstrated that AtHAK5 is localized to the plasma membrane under conditions of K + deprivation, when it is expressed. Growth analysis showed that AtHAK5 plays a role during severe K + deprivation. csc mc rehabilitation leave
