Bacteriophage λ protein phosphatase (λPP) with Mn2+ as the activating metal cofactor was studied using phosphatase inhibition kinetics and electron paramagnetic resonance (EPR) spectroscopy. Orthophosphate and the oxoanion analogues orthovanadate, tungstate, molybdate, arsenate, and sulfate were shown to inhibit the phosphomonoesterase activity of λPP, albeit with inhibition constants (Ki) that...

Purple urine bag syndrome (PUBS) occurs in catheterized patients with bacterial urinary infections that produce sulphatase/ phosphatase. The presence of indigo and indirubin pigments, which are tryptophan metabolites, causes the purple coloring. After antibiotic therapy, colour reverts to normal. We present a case report unusual phenomenon occurring 60-year-old woman carcinoma cervix. She did n...

Low phosphorus increases acid phosphatase activity and transfers soluble from the underground to above-ground, but also inhibits growth development of Moso bamboo root system. Purple (PAP), a kind phosphatase, plays an important role in (P) uptake metabolism. In our study PAP gene family, we identified 17 genes (PePAP) entire genome further analyzed their physical chemical properties functions ...

Purple urine bag syndrome (PUBS) was first reported in 1978. PUBS is rare, occurs predominantly in constipated women, chronically catheterized and associated with some bacterial urinary infections that produce sulphatase/phosphatase. The etiology is due to indigo (blue) and indirubin (red) or to their mixture that becomes purple. A chain reaction begins in the gastrointestinal tract with trypto...
