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 کاملA protein tyrosine phosphatase-like protein from baculovirus has RNA 5'-triphosphatase and diphosphatase activities.
The superfamily of protein tyrosine phosphatases (PTPs) includes at least one enzyme with an RNA substrate. We recently showed that the RNA triphosphatase domain of the Caenorhabditis elegans mRNA capping enzyme is related to the PTP enzyme family by sequence similarity and mechanism. The PTP most similar in sequence to the capping enzyme triphosphatase is BVP, a dual-specificity PTP encoded by...
متن کاملChemical rescue of protein tyrosine phosphatase activity.
We report that the activity of a rationally engineered protein tyrosine phosphatase (PTP) mutant can be fully rescued by the addition of the biarsenical fluorescein derivative FlAsH, a compound that does not affect the activity of wild-type PTPs.

متن کاملHigh sequence homology between protein tyrosine acid phosphatase from boar seminal vesicles and human prostatic acid phosphatase.
Boar seminal vesicle protein tyrosine acid phosphatase (PTAP) and human prostatic acid phosphatase (PAP) show high affinity for protein phosphotyrosine residues. The physico-chemical and kinetic properties of the boar and human enzymes are different. The main objective of this study was to establish the nucleotide sequence of cDNA encoding boar PTAP and compare it with that of human PAP cDNA. A...
