  • PROTEIN
  • In addition, investigation of the thermostability of plastocyanin by the insertion of a disulfide bond indicated an increased stability of the type 1 Cu site in one mutant and resulted in changes in crystallisation properties of the protein. (chalmers.se)
  • Plastocyanin-like domain containing protein. (go.jp)
  • Zn resupply restored Cu homeostasis concomitant with reduced abundance of these structures.Cu isotope labeling demonstrated that sequestered Cu(+) became bioavailable for the synthesis of plastocyanin, and transcriptome profiling indicated that mobilized Cu became visible to CRR1.Cu trafficking to intracellular accumulation sites may be a strategy for preventing protein mismetallation during Zn deficiency and enabling efficient cuproprotein metallation or remetallation upon Zn resupply.

  • Oxidized state of plastocyanin which is a copper-containing protein which most probably freely moves in lumen. (e-photosynthesis.org)
  • Cytochrome f then transfers an electron to the blue-colored copper protein plastocyanin (PC), which in turn reduces oxidized P700 of PSI. (3rbforex.com)
  • proteins
  • Plastocyanin from spinach and nitrite reductase from Rhodobacter sphaeroides 2.4.3 are two copper-containing proteins that are involved in biological electron transport chains: plastocyanin operates in photosynthesis and nitrite reductase takes part in the denitrification pathway. (chalmers.se)
  • Isokinetic correlation of DeltaH and DeltaS parameters and Coulombic energies of the various configurations of the Zncyt/pc(II) complex consistently show that the rearrangement is a facile configurational fluctuation of the associated proteins, qualitatively the same process regardless of the mutations in plastocyanin.

  • 00-116.0 cP) at 283.2 and 293.2 K. We also report the effects of the plastocyanin mutations on the association constant (Ka) and the corresponding free energy of association (DeltaGa) with zinc cytochrome c at 298.2 K. Dependence of kF on temperature yielded the activation parameters DeltaH, DeltaS, and DeltaG. (diva-portal.org)
