Product Description
Carbonic Anhydrase XIII Human Recombinant
Overview
Carbonic Anhydrase XIII, also known as CA13 is a member of the alpha-carbonic anhydrase family, which catalyzes the rapid interconversion of carbon dioxide and water to bicarbonate and protons, a reversible reaction which occurs relatively slowly in the absence of catalyst. Furthermore, the active site of nearly all carbonic anhydrases contains a zinc ion; they have been classified as metalloenzymes. At least five distinct CA families (?, ?, ?, ? and ?) have been found. These families have no significant a.a sequence resemblance and in just about all cases are considered to be an example of convergent evolution. The ?-CAs have been demonstrated in humans.
Biological Activity
Specific activity is > 2,500 pmol/min/ug, and is defined as the amount of enzyme that hydrolyze 1.0 pmole of 4-nitrophenyl acetate to 4-nitrophenol per minute at pH 7.5 at 37C.
Specifications
