Metalloproteins Containing Cytochrome, Iron–Sulfur, or Copper Redox Centers

Interaction of Redox Metalloproteins with Hematite Surfaces

Towards an all-copper redox flow battery based on a copper-containing ionic liquid.

The first redox flow battery (RFB), based on the all-copper liquid metal salt [Cu(MeCN)4][Tf2N], is presented. Liquid metal salts (LMS) are a new type of ionic liquid that functions both as solvent and electrolyte. Non-aqueous electrolytes have advantages over water-based solutions, such as a larger electrochemical window and large thermal stability. The proof-of-concept is given that LMSs can ...

Tuning heme redox potentials in the cytochrome C subunit of photosynthetic reaction centers.

The photosynthetic reaction center (RC) from Rhodopseudomonas viridis contains four cytochrome c hemes. They establish the initial part of the electron transfer (ET) chain through the RC. Despite their chemical identity, their midpoint potentials cover an interval of 440 mV. The individual heme midpoint potentials determine the ET kinetics and are therefore tuned by specific interactions with t...

Formation of the redox cofactor centers during Cox1 maturation in yeast cytochrome oxidase.

The biogenesis of cytochrome c oxidase initiates with synthesis and maturation of the mitochondrion-encoded Cox1 subunit prior to the addition of other subunits. Cox1 contains redox cofactors, including the low-spin heme a center and the heterobimetallic heme a(3):Cu(B) center. We sought to identify the step in the maturation of Cox1 in which the redox cofactor centers are assembled. Newly synt...
