Cupriavidus metallidurans

C. metallidurans plays a vital role, together with Delftia acidovorans, in the formation of gold nuggets. It precipitates metallic gold from a solution of gold(III) chloride, a compound highly toxic to most other microorganisms.

The drug phencyclidine (PCP or ‘Angel Dust’) antagonizes glutamic acid non-competitively at the NMDA receptor

The drug phencyclidine (more commonly known as PCP or ‘Angel Dust’) antagonizes glutamic acid non-competitively at the NMDA receptor. For the same reasons, dextromethorphan and ketamine also have strong dissociative and hallucinogenic effects. Acute infusion of the drug LY354740 (also known as eglumegad, an agonist of the metabotropic glutamate…

Oxalyldiaminopropionic acid (ODAP) is a structural analogue of the neurotransmitter glutamate found in the grass pea Lathyrus sativus

Oxalyldiaminopropionic acid (ODAP) is a structural analogue of the neurotransmitter glutamate found in the grass pea Lathyrus sativus. It is the neurotoxin responsible for the motor neuron degeneration syndrome lathyrism. Woldeamanuel, Yohannes W.; Hassan, Anhar; Zenebe, Guta (2011-11-12). “Neurolathyrism: two…

Tryptophan tryptophylquinone (TTQ) formation

Tryptophan tryptophylquinone (TTQ) is an enzyme cofactor, generated by posttranslational modification of amino acids within the protein. Methylamine dehydrogenase (MADH), an amine dehydrogenase, requires TTQ for its catalytic function. From Wikipedia where this page was last updated June 22,…

Kaede (protein)

Kaede is a photoactivatable fluorescent protein naturally originated from a stony coral, Trachyphyllia geoffroyi. Its name means “maple” in Japanese. With the irradiation of ultraviolet light (350–400 nm), Kaede undergoes irreversible photoconversion from green fluorescence to red fluorescence. Kaede is a homotetrameric protein with…

Nucleic acid secondary structure

Nucleic acid secondary structure is the basepairing interactions within a single nucleic acid polymer or between two polymers. It can be represented as a list of bases which are paired in a nucleic acid molecule.…

Structural motif

In a chain-like biological molecule, such as a protein or nucleic acid, a structural motif is a common three-dimensional structure that appears in a variety of different, evolutionarily unrelated molecules. Johansson, M.U. (23 July 2012). “Defining and searching for structural motifs…

Turn (biochemistry)

For beta turns, see Beta turn. A turn is an element of secondary structure in proteins where the polypeptide chain reverses its overall direction. Definition According to one definition, see Rose et al. 1985 in…

ÎČ turns (also ÎČ-bends, tight turns, reverse turns, Venkatachalam turns) are the most common form of turns—a type of non-regular secondary structure in proteins that cause a change in direction of the polypeptide chain

ÎČ turns (also ÎČ-bends, tight turns, reverse turns, Venkatachalam turns) are the most common form of turns—a type of non-regular secondary structure in proteins that cause a change in direction of the polypeptide chain. They are very common motifs…

Freemartins

A freemartin or free-martin (sometimes martin heifer) is an infertile female cattle with masculinized behavior and non-functioning ovaries.[1] Phenotypically, the animal appears female, but various aspects of female reproductive development are altered due to acquisition of anti-MĂŒllerian hormone from the male twin.[2]  Genetically, the animal is chimeric: karyotypy of…
