The glycosylphosphatidylinositol-anchored phosphatase from Spirodela oligorrhiza is a purple acid phosphatase.
We recently presented clear evidence that the major low-phosphate-inducible phosphatase of the duckweed Spirodela oligorrhiza is a glycosylphosphatidylinositol (GPI)-anchored protein, and, to our knowledge, is the first described from higher plants (N. Morita, H. Nakazato, H. Okuyama, Y. Kim, G.A. Thompson, Jr. [1996] Biochim Biophys Acta 1290: 53-62). In this report the purified 57-kD phosphat...
متن کاملFunctional Assessment of an Overexpressed Arabidopsis Purple Acid Phosphatase Gene (Atpap26) in Tobacco Plants
Background: Overexpression of known genes encoding key phosphate (Pi)-metabolizing enzymes, such as acid phosphatases (APases), is presumed to help plants with Pi availability and absorption as they are mostly exposed to suboptimal environmental conditions for this vital element.Objectives: In this study, the overexpression effect of AtPAP26, one of the m...
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 کاملImproving Phosphorus Efficiency in Crops with Focus on Purple Acid Phosphatase: Potentials and Perspective
Low-phosphorus (P) stress as a key factor limiting plant growth and production is common in most agricultural soils. Most of the soil-applied phosphate will be rapidly immobilized and most of annually applied phosphate fertilizers are fixed in the soil in organic forms by adsorption, sedimentation and transformation. However, excess P application may lead to contamination of water sources by en...

Background: The present study was carried out on the human population of Kashmir valley to evaluate the status of the biochemical parameters of infected population. Materials and Methods: Blood samples were collected from 514 individuals, 298 (57.97%) males and 216 (42.02%) females, 187 (36.38%) were found sero-positive for human toxocariasis. Results: Alkaline phosphatase level was found highe...
