Differential Metabolic Stability of 4α,25- and 4β,25-Dihydroxyvitamin D₃ and Identification of Their Metabolites

Biomolecules, 2023
Vitamin D3 (1) is metabolized by various cytochrome P450 (CYP) enzymes, resulting in the formation of diverse metabolites. Among them, 4α,25-dihydroxyvitamin D3 (6a) and 4β,25-dihydroxyvitamin D3 (6b) are both produced from 25-hydroxyvitamin D3 (2) by ...

The derivation of the formyl-group oxygen of chlorophyll b in higher plants from molecular oxygen. [PDF]

, 1994
The mechanism of formation of the formyl group of chlorophyll b has long been obscure but, in this paper, the origin of the 7-formyl-group oxygen of chlorophyll b in higher plants was determined by greening etiolated maize leaves, excised from dark-grown

Functional interference (crosstalk) between gut microbiome, proteolysis, apoptosis and muscle hypertrophy: Role of resistance training and supplement [PDF]

Journal of Exercise & Organ Cross Talk
Primary objective of this study was to examine the interplay between grip strength, a functional marker of hypertrophy, and its connection to the Firmicutes to Bacteroidetes ratio in the gut microbiome. Twenty-five male Wistar rats were divided into five

Partial mtDNA sequencing data of vulnerable Cephalopachus bancanus from the Malaysian Borneo

Data in Brief, 2019
Tarsier is an endangered nocturnal primate in the family Tarsiidae and is an endemic to Sundaic islands of Philippine (Carlito syrichta), Sulawesi (Tarsius tarsier-complex) and Borneo (Cephalopachus bancanus). Recent records indicated that most molecular

Phylogenetic reconstruction of Syntermitinae (Isoptera, Termitidae) based on morphological and molecular data. [PDF]

PLoS ONE, 2017
The subfamily Syntermitinae comprises a group of Neotropical termites with 18 genera and 101 species described. It has been considered a natural group, but relationships among the genera within the subfamily remain uncertain, and some genera appear to be

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 ...

A preliminary characterization of Bembidion perspicuum LeConte, with a reclassification of related species (Coleoptera, Carabidae) north of México

ZooKeys, 2010
Bembidion perspicuum LeConte is a species distinct from B. transversale Dejean, with which it has been synonymized in the past. In the United States, B. perspicuum occurs from Oregon through Texas along the shores of rivers and creeks. We show that it is

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 ...

Breaking tolerance to the natural human liver autoantigen cytochrome P450 2D6 by virus infection [PDF]

, 2008
Autoimmune liver diseases, such as autoimmune hepatitis (AIH) and primary biliary cirrhosis, often have severe consequences for the patient. Because of a lack of appropriate animal models, not much is known about their potential viral etiology. Infection
