Native Porcine L-Lactate Dehydrogenase LAB GRADE 1

A lactate dehydrogenase (LDH or LD) is an enzyme found in nearly all living cells (animals, plants, and prokaryotes). LDH catalyzes the conversion of pyruvate to lactate and back, as it converts NADH to NAD+ and back. A dehydrogenase is an enzyme that transfers a hydride from one molecule to another.

Cyclooxygenase 1 from Human, Recombinant LAB GRADE 1

 

COX-1 catalyzes the conversion of arachidonic acid to prostaglandin H2 (the first step in the biosynthesis of prostaglandins, thromboxanes, and prostacyclins). It is involved in the homeostatic role of eicosanoids and constitutively almost all animal tissues. Has an apparent KM of 8.3 μM for arachidonic acid.

Native Bovine Protamine Kinase, Cytosolic LAB GRADE 1

 

Cytosolic protamine kinase is involved in the regulation of protein synthesis and is indirectly associated with numerous cellular processes. Cytosolic protamine kinase is a distinct insulin-stimulated kinase involved in the phosphorylation of eukaryotic Initiation Factor 4E (eIF4E) which is key to initiating translation by mRNA. This protein appears to be inactivated by protein phosphatase 2A family members and may also be inhibited by microcystin, okadeic acid, and ATP. The phosphorylation process is reversible and MBPK1 and MBPK2 (Myelin Basic Protein Kinase 1 and 2) may reactivate cytosolic protamine kinase.
