The Crystal Structure of the Extracellular 11-heme Cytochrome UndA Reveals a Conserved 10-heme Motif and Defined Binding Site for Soluble Iron Chelates [PDF]
, 2012 Members of the genus Shewanella translocate deca- or undeca-heme cytochromes to the external cell surface thus enabling respiration using extracellular minerals and polynuclear Fe(III) chelates.

Redox linked flavin sites in extracellular decaheme proteins involved in microbe-mineral electron transfer [PDF]
, 2015 Extracellular microbe-mineral electron transfer is a major driving force for the oxidation of organic carbon in many subsurface environments. Extracellular multi-heme cytochromes of the Shewenella genus play a major role in this process but the mechanism

Structure of a bacterial cell surface decaheme electron conduit [PDF]
, 2011 Some bacterial species are able to utilize extracellular mineral forms of iron and manganese as respiratory electron acceptors. In Shewanella oneidensis this involves decaheme cytochromes that are located on the bacterial cell surface at the termini of ...

Cytochrome P450associated with insecticide resistance catalyzes cuticular hydrocarbon production in Anopheles gambiae. [PDF]
, 2016 The role of cuticle changes in insecticide resistance in the major malaria vector Anopheles gambiae was assessed. The rate of internalization of 14C deltamethrin was significantly slower in a resistant strain than in a susceptible strain.

The interactions of cytochrome c and porphyrin cytochrome c with cytochrome c oxidase. The resting, reduced and pulsed enzymes [PDF]
European Journal of Biochemistry, 1986 Cytochrome c oxidase forms tight binding complexes with the cytochrome c analog, porphyrin cytochrome c. The behaviour of the reduced and pulsed forms of the oxidase with porphyrin cytochrome c have been followed as functions of ionic strength; this behaviour has been compared with that of the resting oxidase [Kornblatt, Hui Bon Hoa and English (1984 ...

Cytochrome c signalosome in mitochondria [PDF]
European Biophysics Journal, 2011 Cytochrome c delicately tilts the balance between cell life (respiration) and cell death (apoptosis). Whereas cell life is governed by transient electron transfer interactions of cytochrome c inside the mitochondria, the cytoplasmic adducts of cytochrome c that lead to cell death are amazingly stable.
