Recombinant Human ALDH2

• Cat.No.: ALDH2-27037TH
• Product Overview: Recombinant full length mature Human ALDH2; amino acids 18-517 , 54.5kDa.

Specification

• Species: Human
• Source: E.coli
• Tag: Non
• Protein Length: 18-517 a.a.
• Description: This protein belongs to the aldehyde dehydrogenase family of proteins. Two major liver isoforms of aldehyde dehydrogenase, cytosolic and mitochondrial, can be distinguished by their electrophoretic mobilities, kinetic properties, and subcellular localizations. A remarkably hig-her frequency of acute alcohol intoxication among Orienta-ls than among Caucasians could be related to the absence of a catalytically active form of the mitochondrial isozyme. The in-crea-sed exposure to acetaldehyde in individuals with the cat-alyti-cally inactive form may also confer greater susceptibility to many types of cancer. This gene encodes a mitochondrial isoform, which has a low Km for acetaldehydes, and is localized in mitochondrial matrix. Alternative splicing results in mu-ltiple transcript variants encoding distinct isoforms.
• Biologicalactivity: Specific activity is < 0.2 units/ml, and was obtained by measuring the increase of NADP in absorbance at 340 nm resulting from the reduction of NAD. One unit will oxidize 1.0 umole of acetaldehyde to acetic acid per minute at pH 8.0 at 25C in the presence of beta-NAD, potassium and thiols.
