Ornithine transcarbamoylase (OTC) (also called ornithine carbamoyltransferase) is an enzyme that catalyzes the reaction between carbamoyl phosphate (CP) and ornithine (Orn) to form citrulline (Cit) and phosphate (Pi). In plants […]

Fructose bisphosphatase (EC 3.1.3.11) is an enzyme that converts fructose-16-bisphosphate to fructose 6-phosphate in gluconeogenesis and the Calvin cycle which are both anabolic pathways. Fructose bisphosphatase catalyses the reverse of […]

Uridine monophosphate synthetase (UMPS) (orotate phosphoribosyl transferase and orotidine-5′-decarboxylase) is the enzyme (EC 4.1.1.23) that catalyses the formation of uridine monophosphate (UMP) an energy-carrying molecule in many important biosynthetic pathways. […]

C-reactive protein (CRP) is an annular (ring-shaped) pentameric protein found in the blood plasma the levels of which rise in response to inflammation (i.e. C-reactive protein is an acute-phase protein).

Intrinsic factor (IF) also known as gastric intrinsic factor (GIF) is a glycoprotein produced by the parietal cells of the stomach. It is necessary for the absorption of vitamin B12 […]

Luciferase is a generic term for the class of oxidative enzymes used in bioluminescence and is distinct from a photoprotein. The name is derived from Lucifer the root of which […]

In molecular biology human chorionic gonadotropin (hCG) is a hormone produced by the syncytiotrophoblast a component of the fertilized egg after conception. Following implantation the syncytiotrophoblast gives rise to the […]

Caspases or cysteine-aspartic proteases or cysteine-dependent aspartate-directed proteases are a family of cysteine proteases that play essential roles in apoptosis (programmed cell death) necrosis and inflammation.Caspases are essential in cells […]

Metallothionein (MT) is a family of cysteine-rich low molecular weight (MW ranging from 500 to 14000 Da) proteins. They are localized to the membrane of the Golgi apparatus.

Orexin also called hypocretin is a neurotransmitter that regulates arousal wakefulness and appetite. The most common form of narcolepsy in which the sufferer briefly loses muscle tone (cataplexy) is caused […]
