Requirement for ω and (ω–1)-hydroxylations of fatty acids by human cytochromes P450 2E1 and 4A11

Journal of Lipid Research, 1999
Human liver microsomes and recombinant human P450 have been used as enzyme source in order to better understand the requirement for the optimal rate of ω and (ω–1)-hydroxylations of fatty acids by cytochromes P450 2E1 and 4A.

The cytochromes of mitochondria from Tetrahymena pyriformis strain ST. [PDF]

, 1972
Mitochondria of the obligately aerobic ciliate protozoon, Tetrahymena pyriformis strain ST, are unusual in that they possess a cytochrome oxidase system that does not react with reduced mammalian cytochrome c; the presence of cytochromes a(603)+a(3) is ...

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

The cryoEM structure of cytochrome bd from C. glutamicum provides novel insights into structural properties of actinobacterial terminal oxidases

Frontiers in Chemistry, 2023
Cytochromes bd are essential for microaerobic respiration of many prokaryotes including a number of human pathogens. These enzymes catalyze the reduction of molecular oxygen to water using quinols as electron donors.

Formation of nanoscale elemental silver particles via enzymatic reduction by Geobacter sulfurreducens

, 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

Unfolding cytochromes c-b₅₆₂ and Rd apo b₅₆₂ [PDF]

, 2020
We have analyzed the early stages of unfolding of cytochromes c-b₅₆₂ (PDB ID: 2BC5) and Rd apo b₅₆₂ (PDB ID: 1YYJ). Our geometrical approach proceeds from an analysis of the crystal structure reported for each protein. We quantify, residue-by-residue and

Effect of b-itc1-site inhibitors on the midpoint potentials of mitochondrial cytochromes b

, 1983
Anaerobic potentiometric titrations of b cytochromes have been carried out in beef heart submitochondrial particles in the presence of several specific inhibitors of electron transfer through the b-c1-site of the respiratory chain.

A Third Way of Energy Conservation in Acetogenic Bacteria

Microbiology Spectrum, 2022
Acetogenic bacteria are a group of strictly anaerobic bacteria that make a living from acetate formation from two molecules of CO2 via the Wood-Ljungdahl pathway (WLP).

The functional localization of cytochromes b in the respiratory chain of anaerobically grown Proteus mirabilis

, 1986
The functional localization of the cytochromes b found in anaerobically grown Proteus mirabilis was investigated. From light absorption spectra, scanned during uninhibited and HQNO-inhibited electron transport to various electron acceptors, it was ...
