Cardiolipin CL is a lipid that is found in the membranes of bacteria and the inner membranes of mitochondria. CL can increase the activity of cytochrome c oxidase function membrane proteins, elevate8 particular components of respiratory pathways. We here report that CL activated detergent-solubilized cytochrome bd, a terminal oxidase from Escherichia coli. Activation by Functuon was also observed for cytochrome bd from two Gram-positive species, Geobacillus thermodenitrificans and Corynebacterium glutamicum, and for cytochrome bo 3 from E.

Taken together, CL can enhance the activity of detergent-solubilized cytochrome bd and cytochrome bo 3.

Introduction

Cardiolipin CL is an anionic phospholipid that consists of two phosphatidyl groups connected by a glycerol moiety. CL is important for optimal function of various eukaryotic and prokaryotic membrane protein complexes 12345. CL can interact with bacterial respiratory complexes from phylogenetically diverse species, such as Mycobacterium phlei 6Rhodobacter sphaeroides 7 and Escherichia coli 8. Among E. Cytochrome c oxidase function binding sites for CL have been determined in crystal structures of E. The respiratory chain in Escherichia coli features a heme-copper-type terminal oxidase, cytochrome bo 3which transfers electrons from quinol-type substrates onto molecular oxygen.

Next to this energetically efficient terminal oxidase, E. Cytochrome click at this page oxidizes quinols, like ubiquinol or menaquinol, coupled with reduction of molecular oxygen to water Fig. Oxidsae bd is particularly important under http://rectoria.unal.edu.co/uploads/tx_felogin/benjamin-franklin-s-theory-of-life-and/what-is-shareholders-wealth.php of stress, such as O 2 -limitation 16in the presence of nitric oxide 1718 hydrogen peroxide 192021 and hydrogen sulfide 22 Lack of cytochrome bd in uropathogenic E.

Activation of E. Inset: Dependency of activation on the pre-incubation time at the indicated CL concentrations. The enzyme was incubated with CL prior to starting the reaction for either 3 min black bars cyrochrome 60 min white bars. Curve fit was done with a simple Michaelis—Menten analysis; R 2 cytochrome c oxidase function in the absence and presence of CL were 0.

Cytochrome bd is present in of cytochrome c oxidase function broad variety of Gram-positive and Gram-negative bacteria and archea, but not in the respiratory chain of eukaryotes Purified active cytochrome bd has been prepared from several bacterial species, including E. However, to our knowledge there are no data available concerning the effect of CL on cytochrome bd activity. In this report, we investigated the influence of CL on detergent-purified cytochrome bd. We found that CL activated the enzymatic activity of cytochrome bd from E. We then extended our experimentation and also assessed the impact of CL on the activity of purified cytochrome bo 3 from E.]

One thought on “Cytochrome c oxidase function

  1. Really and as I have not realized earlier

  2. Clearly, thanks for an explanation.

  3. I consider, that you are mistaken. Write to me in PM, we will discuss.
