Cytochrome b558 of Bacillus subtilis

open access: yes, 1988
The membranebound tricarboxylic acid cycle enzyme succinate dehydrogenase (SDH) is associated with a b-type cytochrome in many organisms. 1,2 The cytochrome b is often found in stoichiometric amounts in isolated succinate-ubiquinone oxidoreductase ...

Priapism, pomegranate juice, and sildenafil: Is there a connection?

open access: yesUrology Annals, 2012
We report the development of low flow priapism in three patients related to simultaneous consumption of sildenafil with pomegranate (Punica granatum) (POM) juice.

Studies on Regioselective Binding Mode of Steroid Molecules in Homology Modeled Cytochrome P450-2C11

open access: yes, 2009
In this study, we investigated the regioselective binding mode of steroid molecules and structure requirements for steroid molecules for 16[alpha]-hydroxylation by Cytochrome P450-2C11.

Unfolding and refolding of cytochrome c driven by the interaction with lipid micelles [PDF]

open access: yes, 2000
Binding of native cyt c to L-PG micelles leads to a partially unfolded conformation of cyt c. This micelle-bound state has no stable tertiary structure, but remains as -helical as native cyt c in solution.

A model of brain circulation and metabolism: NIRS signal changes during physiological challenges [PDF]

open access: yes, 2008
We construct a model of brain circulation and energy metabolism. The model is designed to explain experimental data and predict the response of the circulation and metabolism to a variety of stimuli, in particular, changes in arterial blood pressure, CO2

MOM19, an import receptor for mitochondrial precursor proteins [PDF]

open access: yes, 1989
We have identified a 19 kd protein of the mitochondrial outer membrane (MOM19). Monospecific IgG and Fab fragments directed against MOM19 inhibit import of precursor proteins destined for the various mitochondrial subcompartments, including porin ...

Cytochrome c binding affects the conformation of cytochrome a in cytochrome c oxidase.

open access: yesJournal of Biological Chemistry, 1992
Second derivative absorption spectroscopy has been used to assess the effects of complex formation between cytochrome c and cytochrome c oxidase on the conformation of the cytochrome a cofactor. When ferrocytochrome c is complexed to the cyanide-inhibited reduced or mixed valence enzyme, the conformation of ferrocytochrome a is affected.

In vivo effect of dried chicory root (Cichorium intybus L.) on xenobiotica metabolising cytochrome P450 enzymes in porcine liver

open access: yes, 2011
Cytochrome P450 (CYP) enzymes are widely studied for their involvement in metabolism of drugs and endogenous compounds. In porcine liver, CYP1A2,2Aand 2E1 are important for the metabolism of skatole.Feeding chicory roots to pigs is known to decrease the ...

The Respiratory Chain In Neisseria Species [PDF]

open access: yes, 2013
This work presents the organization of respiratory chain in Neisseria species. The localization of redox proteins was determined. Lipid-modified azurin (Laz) and nitrite reductase (AniA) are mainly associated with outer membrane.
