A cytochrome of the b group from micrococcus lysodeikticus

Biochimica et Biophysica Acta, 1959
Abstract A method has been devised for separating the cytochrome b component of M. lysodeikticus from the other cytochromes. The absorption maxima of the reduced component in whole cells, lysates and particulate preparations were at about 560–561 mμ, 525–530 mμ and 429–430 mμ.

Molecular Phylogenetics of the Peromyscus boylii Species Group (Rodentia: Muridae) Based on Mitochondrial Cytochrome b Sequences

Molecular Phylogenetics and Evolution, 2000
Variation in the mitochondrial cytochrome b gene (1143 bp) was examined to estimate the phylogenetic relationships of taxa within the Peromyscus boylii species group. In addition, phylogenetic relationships among the aztecus, boylii, and truei species groups were addressed.

Topography of the Heme Prosthetic Group of Cytochrome b-559 in the Photosystem II Reaction Center

Biochemistry, 1994
The topography of the heme prosthetic group of cytochrome b-559 of the photosystem II reaction center was determined from measurement of the orientation of its alpha- and beta-polypeptides in thylakoid membranes of spinach chloroplasts and in osmotically disrupted cells of the cyanobacterium Synechocystis sp. PCC 6803.

Phylogenetic Relationships of the Fundulus nottii Species Group (Fundulidae, Cyprinodontiformes) as Inferred from the Cytochrome b Gene

Copeia, 1997
The Fundulus nottii species group, commonly known as starhead topminnows, comprises five species of fishes distributed in the Atlantic and Gulf Coastal Plains and in the Mississippi Valley north to Lake Michigan. Allozyme (Cashner et al., 1992) and morphological (Wiley, 1977, 1986; Wiley and Hall, 1975) data support a monophyletic F nottii species ...

Electroanalysis of Cytochrome P450 3A4 Catalytic Properties with Nanostructured Electrodes: The Influence of Vitamin B Group on Diclofenac Metabolism

BioNanoScience, 2011
Application of vitamin B group permits to shorten the longitude of diclofenac (DF) therapy and to reduce the daytime dose of this drug. All the three schemes of treatment with diclofenac—i.e., diclofenac alone, diclofenac plus two tablets of Gitagamp (composition of vitamin B group), and diclofenac plus four tablets of Gitagamp—enabled to achieve ...

The influence of B-group vitamins on monooxygenase activity of cytochrome P450 3A4: Pharmacokinetics and electro analysis of the catalytic properties

Biochemistry (Moscow) Supplement Series B: Biomedical Chemistry, 2012
Simultaneous administration of loading doses of B-group vitamins and diclofenac allow to decrease the daily dose of this drug without reduction of its analgesic effect. In all three schemes of the diclofenac intake (diclofenac alone, diclofenac plus 2 tablets of Gitagamp (a mixture of B-group vitamins), and diclofenac plus 4 tablets of Gitagamp—maximal

Head Group Modulated pH-Responsive Hydrogel of Amino Acid-Based Amphiphiles:  Entrapment and Release of Cytochromecand Vitamin B₁₂

Langmuir, 2008
The present study describes the rational design and synthesis of amino acid-based amphiphilic hydrogelators, which were systemically fine-tuned at the head group to develop pH-responsive hydrogels. To understand the basic structural requirements of a low molecular weight amphiphilic hydrogelator, 10 analogous amphiphiles based on L-phenylalanine and L ...

Self-splicing of a mitochondrial group I intron from the cytochromeb gene of the ascomycetePodospora anserina

Molecular and General Genetics MGG, 1992
We have shown that the second intron of the Podospora mitochondrial gene coding for cytochrome b (Cytb 12) splices autocatalytically, using in vitro transcripts generated from the T7 promoter. The reaction takes place at 37 degrees C in the presence of 50 mM TRIS-HCl pH 7.5, 60 mM MgCl2 and 1 mM GTP but shows a low efficiency even at high KCl ...

Homologous maturase-like proteins are encoded within the group I introns in different mitochondrial genes specifying Yarrowia lipolytica cytochrome c oxidase subunit 3 and Saccharomyces cerevisiae apocytochrome b

Current Genetics, 1994
A mitochondrial cox3 gene in the alkane yeast, Yarrowia lipolytica, encodes a subunit-3 protein of cytochrome c oxidase, and contains a 1044 base-pair-long intron, as compared with the corresponding intronless gene in Saccharomyces cerevisiae. The intron belongs to a group I intron as determined by the cDNA sequence for the splicing sites as well as ...

[132] Cytochrome b group (bacteria)

1955
Publisher Summary This chapter discusses the determination of cytochrome b group form bacteria. The heme-containing pigments that have been called cytochrome b represent a group of proteins which not only differ from one another in physicochemical properties but probably differ as well in their catalytic function in the chain of respiratory enzymes ...
