Protein-induced Folding of a Group I Intron in Cytochrome b Pre-mRNA [PDF]
Journal of Biological Chemistry, 1995 Some group I introns have been shown to be self-splicing in vitro, but perhaps all require proteins for splicing in vivo. Sequence differences affect the stability of secondary structures and may explain why some group I introns function efficiently without protein cofactors while others require them.

Group II twintron: an intron within an intron in a chloroplast cytochrome b-559 gene. [PDF]
The EMBO Journal, 1991 The psbF gene of chloroplast DNAs encodes the beta-subunit of cytochrome b-559 of the photosystem II reaction center. The psbF locus of Euglena gracilis chloroplast DNA has an unusual 1042 nt group II intron that appears to be formed from the insertion of one group II intron into structural domain V of a second group II intron. Using both direct primer

Cytochrome b-based phylogeny of the Praomys group (Rodentia, Murinae): a new African radiation? [PDF]
Comptes Rendus. Biologies, 2002 Complete cytochrome b gene sequences allows, for the first time, establishing a nearly complete phylogeny among the Praomys group sensu lato. The genera Praomys, Mastomys and Stenocephalemys appear paraphyletic. Myomys is polyphyletic and this genus name probably needs to be restricted to its type species, M. verreauxii.

The influence of vitamin B group on monooxygenase activity of cytochrome P450 3A4: pharmacokinetics and electro analysis of catalytic properties [PDF]
Biomeditsinskaya Khimiya, 2011 It was shown that vitamin B group permit to shorten the longitude of diclofenak therapy and to reduce the daytime dose of this drug. All three schemes of diclofenac treatment - only diclofenac, diclofenac plus 2 tablets of Gitagamp (mixture of vitamin B group), and diclofenac plus 4 tablets of Gitagamp - gave maximum value of diclofenal in blood ...

Splicing of group II introns in mRNAs coding for cytochrome b6 and subunit IV in the liverwort Marchantia polymorpha chloroplast genome Exon specifying a region coding for two genes with the spacer region [PDF]
FEBS Letters, 1987 Two genes, petB and petD, encoding cytochrome b 6 and subunit IV of the cytochrome b 6/ƒ complex, respectively, of the chloroplast genome of Marchantia polymorpha, a liverwort, have been mapped between the psbH and rpoA genes and each of the petB and petD genes has been predicted to contain a group II intron in its coding sequence [(1986) Nature 322 ...

PHYLOGENY OF THE PEROGNATHUS LONGIMEMBRIS SPECIES GROUP BASED ON MITOCHONDRIAL CYTOCHROME-b: HOW MANY SPECIES? [PDF]
Journal of Mammalogy, 2005 The Perognathus longimembris species group currently consists of 3 species and approximately 23 subspecies. Members of this species group have been of considerable interest to biologists in both physiological and ecological studies, and several members are threatened with extinction.

Subunits of Bakers' Yeast Cytochrome b2 (
European Journal of Biochemistry, 1971 1.1 to 1.4 residues of lysine were found as N‐terminal amino acid in crystallized cytochrome b2, 1 residue of alanine and variable amounts of lysine as C‐terminal amino acids. Examination of the end groups of the purified S‐carboxymethylated subunits showed that, besides lysine at the N‐terminus in both chains, alanine at the C‐terminal of the light ...

Transient Binding of CO to CuB in Cytochrome c Oxidase Is Dynamically Linked to Structural Changes around a Carboxyl Group: A Time-Resolved Step-Scan Fourier Transform Infrared Investigation [PDF]
Biophysical Journal, 2002 The redox-driven proton pump cytochrome c oxidase is that enzymatic machinery of the respiratory chain that transfers electrons from cytochrome c to molecular oxygen and thereby splits molecular oxygen to form water. To investigate the reaction mechanism of cytochrome c oxidase on the single vibrational level, we used time-resolved step-scan Fourier ...
