COMMENTARY
LITERATURE
malfunction
physiological function
malfunction
deletion of OE5192R produces a mutant strain with virtually no phosphatase activity
malfunction
the ability of living parasites to cleave exogenous adenosine monophosphate and generate adenosine is very largely abolished when SmAP gene expression is suppressed following RNAi treatment targeting the gene
physiological function
-
Daphnia magna eating phosphorus-poor food have significantly higher alkaline phosphatase activity in their bodies compared with individuals eating phosphorus-rich food. By contrast, poor phosphorus-nutrition of Daphnia lowers alkaline phosphatase activity in released materials compared with that measured from their phosphorus-sufficient conspecifics
physiological function
-
in neonatal blood plasma, soluble 5'-nucleotidase and alkaline phosphatase mediate conversion of AMP to adenosine, whereas soluble adenosine deaminase catabolizes adenosine to inosine. Newborn blood plasma demonstrates substantially higher adenosine-generating 5'-nucleotidase and alkaline phosphatase activity and lower metabolizing adenosine deaminase activity than adult plasma. Abundant alkaline phosphatase expressed on the surface of circulating neonatal neutrophils is the dominant AMPase on these cells
