Alkaline Phosphatase (phoA) from Citrobacter

The alkaline phosphatase is a periplasmic homodimeric hydrolase.

3D representation of the alkaline phosphatase from [http://www.rcsb.org/pdb/explore/explore.do?structureId=1ANJ RCSB]

A form of this protein without TEV and poly-HIS tags can be found here.

Usage and Biology

Alkaline phosphatases are used as reporter enzymes in different assays such as Western Blotting and in situ hybridization^[1]. Testing human blood for Alkaline Phosphatase levels is a routine test that can reveal different conditions^[2].

Alkaline phosphatases cleave phosphate groups from organic compounds by hydrolysis while retaining stereochemistry^[3]. A good explanation of the mechanism can be found [http://chemwiki.ucdavis.edu/Organic_Chemistry/Organic_Chemistry_With_a_Biological_Emphasis/Chapter_10%3A_Phosphoryl_transfer_reactions/Section_10.3%3A_Hydrolysis_of__phosphates here].
Alkaline phosphatases, respectively their serum levels, are also related to several diseases e.g. metabolic myopathies and Paget Disease. ^[4]
