mBio, 2013 Mycobacterium tuberculosis depends on aerobic respiration for growth and utilizes an aa3-type cytochrome c oxidase for terminal electron transfer. Cytochrome c maturation in bacteria requires covalent attachment of heme to apocytochrome c, which occurs ...

Vibrational energy relaxation (VER) of a CD stretching mode in cytochrome c [PDF]
arXiv, 2004 We first review how to determine the rate of vibrational energy relaxation (VER) using perturbation theory. We then apply those theoretical results to the problem of VER of a CD stretching mode in the protein cytochrome c. We model cytochrome c in vacuum as a normal mode system with the lowest-order anharmonic coupling elements. We find that, for the ``

Advanced Healthcare Materials, EarlyView.A magnetic microrobot fabricated by Spirulina platensis is proposed to accumulate in tumor regions and generate in situ high calcium concentration and sufficient oxygen. These characteristics of the microrobot present a strategy for triggering calcium overload therapy and chlorophyll‐mediated photodynamic therapy, and such combination resulted in a ...

UV-light effects on cytochrome c modulated by the aggregation state of phenothiazines. [PDF]
PLoS ONE, 2013 The present study shows the factors that modulate the photodamage promoted by phenothiazines. Cytochrome c was irradiated with UV light for 120 min, over a pH range from 4.0 to 8.0, in the absence and in the presence of different concentrations of ...

Imaging cytochrome C oxidase and FoF1-ATP synthase in mitochondrial cristae of living human cells by FLIM and superresolution microscopy [PDF]
arXiv, 2017 Cytochrome C oxidase and FoF1-ATP synthase constitute complex IV and V, respectively, of the five membrane-bound enzymes in mitochondria comprising the respiratory chain. These enzymes are located in the inner mitochondrial membrane (IMM), which exhibits large invaginations called cristae.

Dynamics of protein-protein encounter: a Langevin equation approach with reaction patches [PDF]
, 2008 We study the formation of protein-protein encounter complexes with a Langevin equation approach that considers direct, steric and thermal forces. As three model systems with distinctly different properties we consider the pairs barnase:barstar, cytochrome c:cytochrome c peroxidase and p53:MDM2.

Interaction of Cytochrome C Oxidase with Steroid Hormones
Cells, 2020 Estradiol, testosterone and other steroid hormones inhibit cytochrome c oxidase (CcO) purified from bovine heart. The inhibition is strongly dependent on concentration of dodecyl-maltoside (DM) in the assay.
