Christopher J. Schofield
Christopher Joseph Schofield (also known as Chris Schofield) is the Head of Organic Chemistry at the University of Oxford and a Fellow of the Royal Society. Chris Schofield is a professor of organic chemistry at the University of Oxford, Department of Chemistry and a Fellow of Hertford College. Prof Schofield studied functional, structural and mechanistic understanding of enzymes that employ oxygen and 2-oxoglutarate as a co-substrate. His work has opened up new possibilities in antibiotic research, oxygen sensing, and gene regulation. After work on plant and microbial oxygenases, he studied uncharacterised human oxygenases. His research has identified unanticipated roles for oxygenases in regulating gene expression, importantly in the cellular hypoxic response, and has revealed new post-translational modifications to chromatin and RNA splicing proteins. The work has identified new opportunities for medicinal intervention. Education Chris Schofield attended St Anselm's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chemistry
Chemistry is the science, scientific study of the properties and behavior of matter. It is a natural science that covers the Chemical element, elements that make up matter to the chemical compound, compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a Chemical reaction, reaction with other Chemical substance, substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both Basic research, basic and Applied science, applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties ...

Ankyrin Repeat
The ankyrin repeat is a 33-residue motif in proteins consisting of two alpha helices separated by loops, first discovered in signaling proteins in yeast Cdc10 and ''Drosophila'' Notch. Domains consisting of ankyrin tandem repeats mediate protein–protein interactions and are among the most common structural motifs in known proteins. They appear in bacterial, archaeal, and eukaryotic proteins, but are far more common in eukaryotes. Ankyrin repeat proteins, though absent in most viruses, are common among poxviruses. Most proteins that contain the motif have four to six repeats, although its namesake ankyrin contains 24, and the largest known number of repeats is 34, predicted in a protein expressed by ''Giardia lamblia''. Ankyrin repeats typically fold together to form a single, linear solenoid structure called ankyrin repeat domains. These domains are one of the most common protein–protein interaction platforms in nature. They occur in a large number of functionally diverse ...

Prolyl Hydroxylase
Procollagen-proline dioxygenase, commonly known as prolyl hydroxylase, is a member of the class of enzymes known as alpha-ketoglutarate-dependent hydroxylases. These enzymes catalyze the incorporation of oxygen into organic substrates through a mechanism that requires alpha-Ketoglutaric acid, Fe2+, and ascorbate. This particular enzyme catalyzes the formation of (2''S'', 4''R'')-4-hydroxyproline, a compound that represents the most prevalent post-translational modification in the human proteome. Enzyme mechanism Procollagen-proline dioxygenase catalyzes the following reaction: L-proline + alpha-ketoglutaric acid + O2 → (2''S'', 4''R'')-4-hydroxyproline + succinate + CO2 The mechanism for the reaction is similar to that of other dioxygenases, and occurs in two distinct stages: In the first, a highly reactive Fe(IV)=O species is produced. Molecular oxygen is bound end-on in an axial position, producing a dioxygen unit. Nucleophilic attack on C2 generates a tetrahedral inte ...

HIF Prolyl-hydroxylase
Hypoxia-inducible factor-proline dioxygenase (, ''HIF hydroxylase'') is an enzyme with systematic name ''hypoxia-inducible factor-L-proline, 2-oxoglutarate:oxygen oxidoreductase (4-hydroxylating)''. This enzyme catalyses the following chemical reaction : hypoxia-inducible factor-L-proline + 2-oxoglutarate + O2 \rightleftharpoons hypoxia-inducible factor-trans-4-hydroxy-L-proline + succinate + CO2 Hypoxia-inducible factor-proline dioxygenase contains iron, and requires ascorbate. Hypoxia-inducible factor (HIF) is an evolutionarily conserved transcription factor that allows the cell to respond physiologically to low concentrations of oxygen. A class of prolyl hydroxylases which act specifically on HIF has been identified; hydroxylation of HIF allows the protein to be targeted for degradation. HIF prolyl-hydroxylase has been targeted by a variety of inhibitors that aim to treat stroke, kidney disease, ischemia, anemia, and other important diseases. Clinically observed prolyl hydr ...

Trichoplax
''Trichoplax adhaerens'' is one of the three named species in the phylum Placozoa. The others are ''Hoilungia hongkongensis'' and ''Polyplacotoma mediterranea''. The Placozoa is a basal group of multicellular animals (metazoa). ''Trichoplax'' are very flat organisms around a millimetre in diameter, lacking any organs or internal structures. They have two cellular layers: the top epitheloid layer is made of ciliated «cover cells» flattened toward the outside of the organism, and the bottom layer is made up of cylinder cells that possess cilia used in locomotion, and gland cells that lack cilia. Between these layers is the fibre syncytium, a liquid-filled cavity strutted open by star-like fibres. ''Trichoplax'' feed by absorbing food particles—mainly microbes—with their underside. They generally reproduce asexually, by dividing or budding, but can also reproduce sexually. Though ''Trichoplax'' has a small genome in comparison to other animals, nearly 87% of its 11,514 predi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypoxia-inducible Factors
Hypoxia-inducible factors (HIFs) are transcription factors that respond to decreases in available oxygen in the cellular environment, or Hypoxia (medical), hypoxia. They are only present in ParaHoxozoa, parahoxozoan animals. Discovery The HIF transcriptional complex was discovered in 1995 by Gregg L. Semenza and postdoctoral fellow Guang Wang. In 2016, William Kaelin Jr., Peter J. Ratcliffe and Gregg L. Semenza were presented the Lasker Award for their work in elucidating the role of HIF-1 in oxygen sensing and its role in surviving low oxygen conditions. In 2019, the same three individuals were jointly awarded the Nobel Prize in Physiology or Medicine for their work in elucidating how HIF senses and adapts cellular response to oxygen availability. Structure Most, if not all, oxygen-breathing species express the conservation (genetics), highly conserved transcriptional complex HIF-1, which is a heterodimer composed of an alpha and a beta subunit, the latter being a const ...

Fellow
A fellow is a concept whose exact meaning depends on context. In learned or professional societies, it refers to a privileged member who is specially elected in recognition of their work and achievements. Within the context of higher educational institutions, a fellow can be a member of a highly ranked group of teachers at a particular college or university or a member of the governing body in some universities (such as the Fellows of Harvard College); it can also be a specially selected postgraduate student who has been appointed to a post (called a fellowship) granting a stipend, research facilities and other privileges for a fixed period (usually one year or more) in order to undertake some advanced study or research, often in return for teaching services. In the context of research and development-intensive large companies or corporations, the title "fellow" is sometimes given to a small number of senior scientists and engineers. In the context of medical education in No ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
