Human prostatic acid phosphatase has phosphotyrosyl protein phosphatase activity.
The major secreted isoenzyme of human prostatic acid phosphatase (PAcP) (EC 3.1.3.2), which catalyses p-nitrophenyl phosphate (PNPP) hydrolysis at acid pH values, was found to have phosphotyrosyl protein phosphatase activity since it dephosphorylated three different phosphotyrosine-containing protein substrates. Several lines of evidence are presented to show that the phosphotyrosyl phosphatase...
متن کاملTransfer of iron from uteroferrin (purple acid phosphatase) to transferrin related to acid phosphatase activity.
There is continuing controversy as to whether iron can be exchanged from the purple phosphatase, uteroferrin (Uf), to fetal transferrin (Tf) and whether this process might be of physiological relevance during pregnancy in the pig. Here, iron transfer from Uf to apoTf at pH 7.1 was followed by measuring the loss of acid phosphatase activity from native Uf as a function of incubation conditions a...
متن کاملAcid Phosphatase Activity in Auer Bodies.
UER BODIES and leukocyte granules appear to be closely related structures, on the basis of similarities found in electron microscopi&’2 and histochemical stildies.3’4 One of the enzymes which can be demonstrated in leukocyte granules both by histochemical5’6’7 and biochemical methods8’#{176} is acid phosphatase. Because we considered Auer bodies to be abnormal granules, this study was undertake...
متن کاملSerum acid phosphatase activity in diabetes mellitus.
Lysosomal enzymes acid phosphatase show increase in diabetes mellitus and this is closely related to diabetic metabolic alterations. This was a crosssectional study conducted on 50 diabetic subjects (25 patients with complications and 25 patients without complications) in RIMS hospital during the period from September 2010 to August 2012. Twenty five age and sex matched healthy individual were ...
متن کاملA Deoxyribonucleic Acid Phosphatase-exonuclease from Escherichia Coli. I. Purification of the Enzyme and Characterization of the Phosphatase Activity.
A major problem regarding deoxyribonucleic acid polymerase action is the nature of the deoxyribonucleic acid template. Alterations of DNA may reduce or enhance its priming capacity, and both kinds of change have complicated assays of polymerase purification. When extensively purified polymerase was chromatographed on hydroxylapatite, over 90% of the protein and all the activity, as measured wit...
