Metabolism of sulphonated anthraquinones in rhubarb, maize and celery: the role of cytochromes P450 and peroxidases [PDF]
, 2009 Sulphonated anthraquinones are precursors of many synthetic dyes and pigments, recalcitrant to biodegradation, and thus contaminating many industrial effluents and rivers.

Molecular biology of Bacillus subtilis cytochromes
, 1992 Bacillus subtilis cells must have cytochromes for growth and can synthesize cytochromes of a-, b-, c-, d-, and o-types. After a long lag, our knowledge of the structure, genetics and specific role for these cytochromes is now growing exponentially as the

, 2008 Geobacter sulfurreducens reduced Ag(I) (as insoluble AgCl or Ag+ ions), via a mechanism involving c-type cytochromes, precipitating extracellular nanoscale Ag(0). These results extend the range of metals known to be reduced by Geobacter species and offer

Frontiers in Molecular Biosciences, 2023 Dendroctonus-bark beetles are natural components and key ecological agents of coniferous forests. They spend most of their lives under the bark, where they are exposed to highly toxic terpenes present in the oleoresin.

Cytochromes P450 and drug resistance
, 1993 Cytochromes P450 are the key enzymes for activating and inactivating many drugs, in particular anticancer drugs. Therefore, individual expression levels of cytochromes P450 may play a crucial role in drug safety and drug efficacy.

Mapping of redox state of mitochondrial cytochromes in live cardiomyocytes using Raman microspectroscopy. [PDF]
PLoS ONE, 2012 This paper presents a nonivasive approach to study redox state of reduced cytochromes c, c1 and b of complexes II and III in mitochondria of live cardiomyocytes by means of Raman microspectroscopy. For the first time with the proposed approach we perform

Multi-heme cytochromes—new structures, new chemistry
, 2005 Heme is one of the most pervasive cofactors in nature and the c-type cytochromes represent one of the largest families of heme-containing proteins. Recent progress in bacterial genomic analysis has revealed a vast range of genes encoding novel c-type ...

FEBS Letters, EarlyView.The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes
FEBS Letters, EarlyView.Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics
