Studies were carried out on the properties of phosphatases in the water-soluble fraction of edible marine invertebrates (shellfish, crab, prawn, cuttlefish and octopus).
Two kinds of acid phosphatases are found. One is inhibited by NaF, and little affected by Mg++. The other is activated by Mg++, Mn++ and Co++. Both are active on 2′ (3′) -AMP, β-glycerophosphate as well as on 5′-nucleotides.
Some properties of phosphatases in animal foods were summarized.
