A 71-year-old woman in a nursing home, with indwelling urinary catheter, bedridden, presented with a purple urine collector bag. The purple urine bag syndrome is a rare condition associated with the metabolism of tryptophan by overgrowth of intestinal bacteria. The purple color is formed by a combination of indigo and indirubin produced as a result of phosphatase and sulfatase enzymatic activit...

An intracellular acid phosphatase (IAP) from P(i)-starved (-P(i)) tomato ( Lycopersicon esculentum ) suspension cells has been purified to homogeneity. IAP is a purple acid phosphatase (PAP), as the purified protein was violet in colour (lambda(max)=546 nm) and was insensitive to L-tartrate. PAGE, periodic acid-Schiff staining and peptide mapping demonstrated that the enzyme exists as a 142 kDa...

background: cryptorchidism is a common malformation in neonates; surgery or medical treatments are applied during childhood. untreated cryptorchid testes are in the risk of intratubular germ cell neoplasia (igcn) and consequently invasive testicular tumors which could be shown by immunohistochemistry staining for placental like acid phosphatase (plap) marker. objective: we designed this study t...

Potatoes regarding their consumption are a significant antioxidant source in human nutrition. The main potato antioxidants are polyphenols, ascorbic acid, carotenoids, tocopherols, α-lipoic acid, and selenium. The most contained polyphenolic antioxidants in potatoes are L-tyrosine, caffeic acid, scopolin, chlorogenic and cryptochlorogenic acid and ferulic acid. In red and purple potatoes are in...

The aim of this study was to determine the total phenolic (TP) content and antioxidant activity (AA) in yellow (cvs. Impala, Karin, Dita, Saturna) and purple-fleshed (cvs. Valfi, Violette) potatoes grown in the Czech Republic in 2004 in four locations in precise field trials. TP content was determined by Folin-Ciocalteau assay and AA by DPPH assay both in freeze-dried tuber matter. Results show...

Enhancing the absorption and utilization of phosphorus by crops is an important aim for ensuring food security worldwide. However, gene regulatory network underlying use in foxtail millet remains unclear. In this study, molecular mechanism low-phosphorus (LP) responsiveness was evaluated using a comparative transcriptome analysis. LP reduced chlorophyll content shoots, increased anthocyanin roo...

Sequence profile and fold recognition methods identified mammalian purple acid phosphatase (PAP), a member of a dimetal-containing phosphoesterase (DMP) family, as a remote homolog of human acid sphingomyelinase (ASM). A model of the phosphoesterase domain of ASM was built based on its predicted secondary structure and the metal-coordinating residues of PAP. Due to the low sequence identity bet...
