Blueberry has high nutritional value and is favored by consumers, so the planting area increasing. However, due to influence of climate conditions edaphic environment, achieving production healthy growth blueberries become a major problem. In this study, we collected soil blueberry plants which had normal limited determine underlying causes poor characterizing pH, EC, enzyme activities microbio...

Moraxella catarrhalis O35E was shown to synthesize a 105-kDa protein that has similarity to both acid phosphatases and autotransporters. The N-terminal portion of the M. catarrhalis acid phosphatase A (MapA) was most similar (the BLAST probability score was 10(-10)) to bacterial class A nonspecific acid phosphatases. The central region of the MapA protein had similarity to passenger domains of ...

Acid phosphatase activities in a culture liquid and mycelial extract were studied in submerged cultures of the filamentous fungus Humicola lutea 120-5 in casein-containingmedia with and without inorganic phosphate (Pi). The Pi-repressible influence on the phosphatase formation was demonstrated. Significant changes in the distribution of acid phosphatase between the mycelial extract and culture ...

Seed shriveling in the man-made intergeneric hybrid, triticale (x Triticosecale Wittmack) appears to be related to increased activity of endosperm acid phosphatases including para-nitrophenyl phosphatase, ATPase, ADPase, phosphatidic phosphatase, and glucose-1-phosphatase that occur specifically at later stages of seed development. These hydrolases may reduce endogenous substrates for starch sy...

Effect of Chlorpyrifos (Dursban) an organophosphate insecticide on the glycogen, cholesterol, protein, alkaline phosphatase and acid phosphatase in liver in Channa punctatus (Bloch) exhibited notable alterations. Liver being the main site of metabolic activity in body and highly active in both toxifying and detoxifying insecticides, was selected for the study purpose. Chlorpyrifos insecticide c...

Francisella tularensis is a highly infectious bacterial pathogen that is considered by the Centers for Disease Control and Prevention to be a potential bioterrorism weapon. Here, the crystallization of a 37.2 kDa phosphatase encoded by the genome of F. tularensis subsp. holarctica live vaccine strain is reported. This enzyme shares 41% amino-acid sequence identity with Legionella pneumophila ma...

A procedure is presented for the automated determination of acid phosphatase activity in biological materials using the Robot Chemist. Although either phenylphosphate and a-naphthylphosphate may be used as substrate in this analysis, the procedure is described in detail for serum acid phosphatase using a-naphthylphosphate in 0.1 M citrate, pH 5.2, since this substrate is more selective for pros...

This report describes the separation of cells exhibiting histochemically demonstrable acid phosphatase from suspensions of cells obtained from human prostatic carcinomas by velocity sedimentation. In the unseparated suspensions of cells, 40.5 +/- 7.7% of nucleated cells contained histochemically evident acid phosphatase. After cells were separated by velocity sedimentation, 86.4 +/- 9.4% of the...

The PAS and acid phosphatase reactions showed a different pattern of positivity in the cells of lymphoproliferative disorders according to their B or T cell nature. In B-cell leukaemias (chronic lymphocytic and prolymphocytic) a low proportion of lymphocytes gave a positive result with the acid phosphatase reaction, while the majority were PAS positive in granular form. In contrast, in the T-pr...

The immunological similarity between human tartrate-resistant acid phosphatase (EC 3.1.3.2) and porcine uteroferrin previously reported for the isoenzyme from spleens of patients with leukemic reticuloendotheliosis (Ketcham et al., J Biol Chem 1985;260:5768-76) has been confirmed for partly purified acid phosphatase found in the spleen of a patient with Gaucher's disease, and for the correspond...
