Protein Kinases

protein kinase is a kinase enzyme that modifies other proteins by chemically adding phosphate groups to them (phosphorylation). Phosphorylation usually results in a functional change of the target protein (substrate) by changing enzyme activity, cellular location, or association with other proteins.

Protein Phosphatases

Protein phosphatases are a group of enzymes, found ubiquitously, which are responsible for the dephosphorylation of various proteins and enzymes in a cell. This role is an extremely important one since protein phosphorylation and dephosphorylation is required for the regulation of a large number of cellular activities.

Protein disulfide isomerase

Protein disulfide isomerase or PDI (EC 5.3.4.1) is an enzyme in the endoplasmic reticulum in eukaryotes that catalyzes the formation and breakage of disulfide bonds between cysteine residues within proteins as they fold.This allows proteins to quickly find the correct arrangement of disulfide bonds in their fully-folded state, and therefore the enzyme acts to catalyze protein folding.

Protein-disulfide reductase

This enzyme participates in glutathione metabolism.

Properties Suppliers
Proteinase K

Proteinase K (EC 3.4.21.64 )is a broad-spectrum serine protease. The predominant site of cleavage is the peptide bond adjacent to the carboxyl group of aliphatic and aromatic amino acids with blocked alpha amino groups. It is commonly used for its broad specificity. This enzyme belongs to Peptidase family S8.

Protoporphyrinogen oxidase

Protoporphyrinogen oxidase (EC 1.3.3.4) is an enzyme that is responsible for the seventh step in heme production. Protoporphyrinogen oxidase removes hydrogen atoms from protoporphyrinogen IX to form protoporphyrin IX.

Properties Suppliers
Putrescine oxidase

Putrescine oxidase (EC 1.4.3.10) is an enzyme that belongs to the family of oxidoreductases, specifically those acting on the CH-NH2 group of donors with oxygen as acceptor. The systematic name of this enzyme class is putrescine:oxygen oxidoreductase (deaminating). This enzyme participates in urea cycle and metabolism of amino groups. It employs one cofactor, FAD.

Pyranose dehydrogenase

Pyranose dehydrogenase catalysis with 1,4-benzoquinone as an oxidant provides biocatalytic sugar chemistry with a new convenient tool for high yield production of 3-keto-oligosaccharides and 3-keto-glycosides.The enzyme also acts on 1-4-a- and 1-4-b-glucooligosaccharides, non-reducing gluco-oligosaccharides and L-arabinose, which are not substrates of EC 1.1.3.10. Sugars are oxidized in their pyranose but not in their furanose form.

Properties Suppliers
Pyridoxal-5-phosphate LAB GRADE 98

Pyridoxal-5-phosphate functions as a coenzyme in the metabolism of amino acids, carbohydrates, lipids, and proteins. https://www.creative-enzymes.com/product/Pyridoxal5phosphate_16267.html

Pyridoxine 4-dehydrogenase

Pyridoxine 4-dehydrogenase (EC 1.1.1.65) is an enzyme that belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is pyridoxine:NADP+ 4-oxidoreductase. This enzyme participates in vitamin B6 metabolism.
