Acid and alkaline phosphatases in their relation to malignant disease.

Acid and Alkaline Phosphatases There are probably many different phosphatases present in living organisms and much valuable data is being accumulated on their identity and methods of differential estimation. In the present state of our knowledge, however, and from the aspect of clinical application, we can best think of them in terms of two groups, the socalled' alkaline ' and' acid' phosphatas...

LOCALIZATION OF ACID AND ALKALINE PHOSPHATASES IN Myxococcus coralloides D

Substrate selectivity in the action of alkaline and acid phosphatases.

Alkaline phosphatase of intestinal origin hydrolyzed the S-substituted monoesters of phosphorothioic acid of the type RSP03Na2 (R = -CH2CH2NH2, -CH,CH,NHCOCH,, -CH,COO, or -CH2CHsCOOCzHs) at the S-P bond to yield orthophosphate and the corresponding thioalcohols. The rate of enzymic hydrolysis of cysteamine S-phosphate was measured at pH 9.0 in 0.1 N sodium barbital buffer at different concentr...

Microbial alkaline phosphatases in bioprocessing

Microorganisms producing alkaline phosphatases are wide spread in nature. Alkaline phosphatase (Orthophosphoric monoester phosphohydrolase, E.C.3.1.3.1) is a hydrolase enzyme functioning at alkaline pH. The metalloenzyme containing the two zinc ions are involved in catalysis whereas the magnesium ion is important in structural stabilization (Simpson et al., 1968; Anderson et al., 1975). The enz...
