Webtransfer (ET) are dominated by the presence of a hydroxide ion as the sixth axial heme iron ligand above pH 6. On both SAMs, protonation of the bound hydroxide ion is mainly responsible for the changes in these parameters at low pH, since the distances of ET between the heme and the electrode are found to be independent of pH in the range of 5 … WebThiolate ligated zinc complexes have been characterized with a co-crystallized methanol molecule that is hydrogen bonded to a zinc-bound sulfur, and the possibility the alcohols may be activated without coordination to the metal center was discussed by Shoner et al.904...

WebCytochromes P450s (CYPs) are terminal enzymes in CYP dependent monooxygenases, which constitute a superfamily of enzymes catalysing the metabolism of both endogenous and exogenous substances. One of their main tasks is to facilitate the excretion of these substances and eliminate their toxicities in most phase 1 reactions. WebThe role of the cysteine thiolate in heme sensor proteins differs from that of the P450 system, in which the cysteine thiolate donates an electron to activate molecular oxygen …
Web8 dec. 2011 · Cytochrome P450s are heme-thiolate proteins involved in the oxidative degradation of various compounds. They can be divided into 4 classes, according to the method by which electrons from NAD(P)H are delivered to the catalytic site. WebHeme peroxidases comprise the classical ligninolytic peroxidases and the new dye-decolorizing peroxidases, while heme peroxygenases belong to a still largely unexplored superfamily of heme-thiolate proteins.
