WebStructures for a number of peroxidase enzymes have been solved (reviewed recently in Poulos 2010).Despite attracting much of the early attention, its heavily glycosylated structure meant that HRP proved very difficult to crystallize, and a structure did not emerge until fairly recently (Gajhede et al. 1997).Cytochrome c peroxidase (CcP), on the other hand, …

WebCytochrome c (551, P. aeruginosa) (Horio et al., 1960) is one of the best studied bacterial cytochromes C. It seems to act in the organism just as mammalian-type cytochrome c does in mitochondria (Yamanaka, 1964). It shows an absorption peak at 409 nm in the oxidized form and peaks at 551, 521, and 416 nm in the reduced forms.
WebOf these only cytochrome c peroxidase has proved stable enough to crystallise with the iron in the ferryl form [26].
