ATP synthase (EC 3.6.3.14) is an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate (ATP). ATP is the most commonly used energy […]

Shiga-like toxin also known as verotoxin is a toxin generated by some strains of Escherichia coli (but see below). It is named for its similarity to the AB5-type Shiga toxin […]

Growth hormone (GH or HGH) also known as somatotropin or somatropin is a peptide hormone that stimulates growth cell reproduction and regeneration in humans and other animals. It is a […]

Ureases (EC 3.5.1.5) functionally belong to the superfamily of amidohydrolases and phosphotriestreases. It is an enzyme that catalyzes the hydrolysis of urea into carbon dioxide and ammonia. The reaction occurs […]

Pepsin is an enzyme whose zymogen (pepsinogen) is released by the chief cells in the stomach and that degrades food proteins into peptides. It was discovered in 1836 by Theodor […]

Ricin /ˈraɪsɪn/ is a highly toxic naturally occurring lectin (a carbohydrate-binding protein) produced in the seeds of the castor oil plant Ricinus communis. A dose the size of a few […]

ATPases (EC 3.6.1.3 adenylpyrophosphatase ATP monophosphatase triphosphatase SV40 T-antigen adenosine 5′-triphosphatase ATP hydrolase complex V (mitochondrial electron transport) (Ca2+ + Mg2+)-ATPase HCO3−-ATPase adenosine triphosphatase) are a class of enzymes that […]

A hexokinase is an enzyme that phosphorylates hexoses (six-carbon sugars) forming hexose phosphate. In most organisms glucose is the most important substrate of hexokinases and glucose-6-phosphate the most important product.Hexokinases […]

Fibronectin is a high-molecular weight (~440kDa) glycoprotein of the extracellular matrix that binds to membrane-spanning receptor proteins called integrins. Similar to integrins fibronectin binds extracellular matrix components such as collagen […]

The green fluorescent protein (GFP) is a protein composed of 238 amino acid residues (26.9 kDa) that exhibits bright green fluorescence when exposed to light in the blue to ultraviolet […]
