Azioni biochim/fisiol

Alkaline phosphatase, from Escherichia coli, is a dimeric, non-glycosylated protein which mainly reside in the periplasmic space. Three known isoforms exist. The enzyme requires zinc, and is activated by magnesium. E. coli akaline phosphatase has a broad specificity for phosphate esters.
