  • protein
  • This work has revealed the pathways, rates, and yields of the electron transfer reactions but has also raised several intriguing questions about how these properties are governed by the protein-cofactor interactions. (schoolbag.info)
  • 2007). In chlorophototrophs, light energy is transduced into chemical potential energy by reaction centers, photo-oxidoreductases that form two families of BChl/Chl-containing, pigment-protein complexes ( Golbeck, 1993 ). (tcdb.org)
  • The ferredoxin-type [2Fe-2S] clusters are coordinated to the protein by four cysteine residues (see PDOC00175 ). (ebi.ac.uk)
  • complexes
  • In both reaction centers, an extensive network of chlorophyll molecules, used to capture light, is housed in the same complex as the electron transfer cofactors, and hence, these complexes are called photosystems. (schoolbag.info)
  • However, we could not observe such differences either in isolated PSI complexes or through PSI-driven electron transport. (biomedcentral.com)
  • molecule
  • Absorption of visible light by a chromophore molecule is known to induce transfer of an electron from the main orbital (S0) to one of the singlet (S1 * , S2 * …) or triplet (T) excited orbitals (Fig. 2.2). (slideshare.net)
