Molybdenum cofactor deficiency

Molybdenum cofactor deficiency (MoCD), types A/B/C from MOCS1, MOCS2, MOCS3, or GPHN mutations, is an autosomal recessive metabolic disease causing sulfite oxidase loss, neonatal seizures, and encephalopathy; fosdenopterin treats type A.

Molybdenum cofactor sulfurase, C-terminal

Molybdenum cofactor sulfurase, C-terminal (MOSC domain, InterPro IPR005302, Pfam PF03473): a β-barrel protein domain with a conserved cysteine that binds sulfurated molybdenum cofactor and activates xanthine oxidase family enzymes; also a widespread molybdoenzyme family (mARC, YiiM, YcbX).

Molybdenum deficiency

Molybdenum deficiency, impairment of molybdenum-dependent enzymes such as sulfite oxidase; dietary deficiency has never been observed in healthy humans, with one 1981 parenteral-nutrition case and the rare genetic molybdenum cofactor deficiency.

Molybdenum dioxide

Molybdenum dioxide, also called molybdenum(IV) oxide (MoO₂), is a gray transition metal oxide with a distorted rutile structure and unusual metallic conductivity, used in lithium-ion battery anodes and gas sensors.

Molybdenum diselenide

Molybdenum diselenide (MoSe₂) is a layered inorganic compound of molybdenum and selenium that can be exfoliated to atomically thin sheets and studied for batteries, catalysis, and optoelectronics.

Molybdenum disilicide

Molybdenum disilicide (MoSi₂) is an intermetallic compound of molybdenum and silicon with a 2030 °C melting point, used for high-temperature electric heating elements and as a candidate structural material.

Molybdenum disulfide

Molybdenum disulfide (MoS2), or molybdic sulfide, is an inorganic compound occurring naturally as molybdenite, the principal ore of molybdenum, and widely used as a solid lubricant.

Molybdenum disulfide hydrogen evolution catalysis

Molybdenum disulfide hydrogen evolution catalysis is the use of MoS2, a layered transition-metal dichalcogenide, as a non-precious electrocatalyst for the hydrogen evolution reaction in water splitting.

Molybdenum disulfide nanosheets

Molybdenum disulfide (MoS₂) nanosheets are ultrathin two-dimensional sheets, typically one to a few atomic layers thick, studied as platforms for drug delivery, photothermal cancer therapy, bioimaging, biosensing, and tissue engineering.

Molybdenum ditelluride

Molybdenum ditelluride (MoTe₂) is a layered transition metal dichalcogenide, about 0.7 nm per layer, whose three crystal phases span semiconductor, metal, and type-II Weyl semimetal behavior.

Molybdenum sulfide CO2 reduction to formate

Molybdenum sulfide CO2 reduction to formate is the conversion of carbon dioxide into formate over molybdenum disulfide catalysts, reported in 2023 with over 99 percent selectivity at 200 °C.

Molybdenum transport protein ModE-like

Molybdenum transport protein ModE-like (InterPro IPR051815): bacterial molybdate-responsive transcriptional regulators, archetype E. coli ModE, a homodimer with winged HTH DNA-binding and Mop molybdate-binding domains that represses modABC and activates molybdoenzyme genes.

Molybdenum trioxide

Molybdenum trioxide (MoO₃) is a colorless to white solid, the highest oxide of molybdenum, made by roasting molybdenite ore and converted into molybdates, catalysts, alloys, and molybdenum metal.

Molybdenum-99

Molybdenum-99 (Mo-99) is a radioactive isotope of molybdenum with a 66-hour half-life whose decay product, technetium-99m, is the most widely used isotope in nuclear medicine imaging.

Molybdopterin

Molybdopterin, also called pyranopterin, is the organic ligand of the molybdenum cofactor, a tricyclic pterin that binds molybdenum or tungsten in nearly all enzymes containing those metals.

Molybdopterin oxidoreductase

Molybdopterin oxidoreductases are enzymes that catalyze oxidation-reduction reactions through the molybdenum cofactor, transferring an oxygen atom between water and a substrate; they occur across nearly all living species.

Molybdopterin synthase sulfur carrier subunit

Molybdopterin synthase sulfur carrier subunit (MOCS2A in humans, MoaD in E. coli) is the ubiquitin-like small subunit of MPT synthase that carries sulfur as a C-terminal thiocarboxylate to build molybdopterin's dithiolene in molybdenum cofactor biosynthesis.

Molybdopterin synthase sulfurylase MoeB

MoeB, the molybdopterin synthase sulfurylase (MSAE) of Escherichia coli, ATP-dependently adenylates the ubiquitin-like sulfur carrier MoaD so IscS can thiocarboxylate it for molybdenum cofactor biosynthesis; its MoeB–MoaD structure (PDB 1JW9) revealed the evolutionary origin of E1-ubiquitin activation.

Molyneux's problem

Molyneux's problem, or Molyneux's question, is a 1688 question from William Molyneux to John Locke asking whether a person born blind could identify by sight alone shapes known only by touch; debated from Cheselden's 1728 case to Held et al. 2011.

Molzbichl

Molzbichl, a village in Spittal an der Drau, Carinthia, Austria, site of the parish church of St. Tiburtius above the oldest monastery in Carinthia (founded after 772 by Tassilo III), the Nonnosus inscription of 533, and the Museum Carantana.

Mom (film)

Mom (मॉम) is a 2017 Hindi-language revenge thriller directed by Ravi Udyawar and starring Sridevi, her 300th film, which won her a posthumous National Film Award for Best Actress.

Mom (TV series)

Mom is a CBS sitcom (2013-2021, 8 seasons) created by Chuck Lorre, Eddie Gorodetsky, and Gemma Baker, starring Anna Faris and Allison Janney as a recovering-alcoholic mother and daughter in Napa Valley.
