A highly complex version of … WebIn the α-, β- and γ-Proteobacteria, the so-called cytochrome c maturation (Ccm) system is known to promote the covalent attachment of the haem to periplasmic apocytochrome c. However, in species of Pseudomonas, Rhizobium, Paracoccus and Legionella, mutations in com genes result in phenotypes that cannot be readily explained by the simple ...
WebEfficient nanomaterials for artificial photosynthesis require fast and robust unidirectional electron transfer (ET) from photosensitizers through charge-separation and accumulation units to redox-active catalytic sites. We explored the ultrafast time-scale limits of photo-induced charge transfer between a Ru(II)tris(bipyridine) derivative photosensitizer and … Webcytochrome c maturation (Ccm) system is known to promote the covalent attachment of the haem to periplasmic apocytochrome c. However, in species of Pseudomonas, …
WebThe cytochrome C maturation (Ccm) system consists of heme delivery proteins that help the conduit proteins, such as the proteins in the MtrCAB operon, to mature properly by translocating heme in the periplasm and catalyzes the formation of thioether bonds that link heme to two cysteine residues. The axial ligands are then coordinated to the ...
