https://en.wikipedia.org/wiki/Dihydroorotase | Dihydroorotase (, carbamoylaspartic dehydrase, dihydroorotate hydrolase) is an enzyme which converts carbamoyl aspartic acid into 4,5-dihydroorotic acid in the biosynthesis of pyrimidines. It forms a multifunctional enzyme with carbamoyl phosphate synthetase and aspartate transcarbamoylase. Dihydroorotase is a zinc met... |
https://en.wikipedia.org/wiki/Orotate%20phosphoribosyltransferase | Orotate phosphoribosyltransferase (OPRTase) or orotic acid phosphoribosyltransferase is an enzyme involved in pyrimidine biosynthesis. It catalyzes the formation of orotidine 5'-monophosphate (OMP) from orotate and phosphoribosyl pyrophosphate. In yeast and bacteria, orotate phosphoribosyltransferase is an independen... |
https://en.wikipedia.org/wiki/DBAG%20Class%20422 | The Class 422 is a series of four-car electric multiple units that are a derivative of the DBAG Class 423. The two inner cars in the set are designated as Class 432 vehicles.
History
The units were commissioned by Deutsche Bahn in 2005. 78 units worth €343 million were built by Bombardier Transportation and Alstom an... |
https://en.wikipedia.org/wiki/Harish-Chandra%27s%20regularity%20theorem | In mathematics, Harish-Chandra's regularity theorem, introduced by , states that every invariant eigendistribution on a semisimple Lie group, and in particular every character of an irreducible unitary representation on a Hilbert space, is given by a locally integrable function. proved a similar theorem for semisimple... |
https://en.wikipedia.org/wiki/Fukushima%27s%20Theorem | In physics, Fukushima's Theorem holds that for all points beneath the ionosphere the magnetic fields from field-aligned currents and their corresponding Pedersen currents exactly cancel. By superposition the total magnetic field at the ground is then equal to the magnetic field from just the ionospheric Hall currents.

https://en.wikipedia.org/wiki/Orotic%20aciduria | Orotic aciduria (AKA hereditary orotic aciduria) is a disease caused by an enzyme deficiency, resulting in a decreased ability to synthesize pyrimidines. It was the first described enzyme deficiency of the de novo pyrimidine synthesis pathway.
Orotic aciduria is characterized by excessive excretion of orotic acid in u... |
https://en.wikipedia.org/wiki/Methylenedioxyallylamphetamine | Methylenedioxyallylamphetamine (MDAL or 3,4-methylenedioxy-N-allylamphetamine) is a lesser-known psychedelic drug. It is also the N-allyl derivative of 3,4-methylenedioxyamphetamine (MDA). MDAL was first synthesized by Alexander Shulgin. In his book PiHKAL, the minimum dosage is listed as 180 mg, and the duration unkno... |
https://en.wikipedia.org/wiki/Problem%20of%20points | The problem of points, also called the problem of division of the stakes, is a classical problem in probability theory. One of the famous problems that motivated the beginnings of modern probability theory in the 17th century, it led Blaise Pascal to the first explicit reasoning about what today is known as an expected... |
https://en.wikipedia.org/wiki/Quartile%20coefficient%20of%20dispersion | In statistics, the quartile coefficient of dispersion is a descriptive statistic which measures dispersion and is used to make comparisons within and between data sets. Since it is based on quantile information, it is less sensitive to outliers than measures such as the coefficient of variation. As such, it is one of s... |
https://en.wikipedia.org/wiki/Implicit%20curve | In mathematics, an implicit curve is a plane curve defined by an implicit equation relating two coordinate variables, commonly x and y. For example, the unit circle is defined by the implicit equation . In general, every implicit curve is defined by an equation of the form
for some function F of two variables. Hence ... |
https://en.wikipedia.org/wiki/Epimerase%20and%20racemase | Epimerases and racemases are isomerase enzymes that catalyze the inversion of stereochemistry in biological molecules.
Racemases catalyze the stereochemical inversion around the asymmetric carbon atom in a substrate having only one center of asymmetry. Epimerases catalyze the stereochemical inversion of the configurat... |

https://en.wikipedia.org/wiki/Purine%20metabolism | Purine metabolism refers to the metabolic pathways to synthesize and break down purines that are present in many organisms.
Biosynthesis
Purines are biologically synthesized as nucleotides and in particular as ribotides, i.e. bases attached to ribose 5-phosphate. Both adenine and guanine are derived from the nucleotid... |
https://en.wikipedia.org/wiki/Xanthosine%20monophosphate | Xanthosine monophosphate also called Xanthylate is an intermediate in purine metabolism. It is a ribonucleoside monophosphate. It is formed from IMP via the action of IMP dehydrogenase, and it forms GMP via the action of GMP synthase. Also, XMP can be released from XTP by enzyme deoxyribonucleoside triphosphate pyropho... |
https://en.wikipedia.org/wiki/GMP%20synthase | Guanosine monophosphate synthetase, () also known as GMPS is an enzyme that converts xanthosine monophosphate to guanosine monophosphate.
In the de novo synthesis of purine nucleotides, IMP is the branch point metabolite at which point the pathway diverges to the synthesis of either guanine or adenine nucleotides. In ... |
