The major storage protein fraction, globulin-1 protein, of French bean (Phaseolus vulgaris L.) was analyzed by two-dimensional electrophoresis. The protein pattern suggested a more complex system for globulin-1 protein than the model of three polypeptides, alpha, beta, and gamma, differing in molecular weight. Isoelectrofocusing analyses of the individual proteins showed that each exhibited cha...

A globulin fraction, isolated from black beans (Phaseolus vulgaris), was resistant to hydrolysis by pepsin, trypsin, chymotrypsin, papain, ficin, hurain, and subtilisin. After denaturation of the globulin by heat or urea, only slight hydrolysis by enzymes could be detected. The activity of all seven proteinases on their respective substrates was inhibited by the bean globulin. Preincubation of ...

The carbohydrate moiety of secretory arabinogalactan protein in bean seedlings (Phaseolus vulgaris L. cv. Prélude) is attached to the peptide backbone through hydroxyproline, serine, and threonine. Hydroxyproline-linked side chains, consisting of arabinose, galactose, glucose, and rhamnose, comprise the major part of the sugar residues. These hydroxyproline glycosides differ from those in non-e...

Ensifer adhaerens is a soil bacterium that attaches to other bacteria and may cause lysis of these other bacteria. Based on the sequence of its small-subunit rRNA gene, E. adhaerens is related to Sinorhizobium spp. E. adhaerens ATCC 33499 did not nodulate Phaseolus vulgaris (bean) or Leucaena leucocephala, but with symbiotic plasmids from Rhizobium tropici CFN299 it formed nitrogen-fixing nodul...

We show that the expression of an indole-3-acetic acid (IAA)-modified protein from bean seed, IAP1, is correlated to the developmental period of rapid growth during seed development. Moreover, this protein undergoes rapid degradation during germination. The gene for IAP1, the most abundant protein covalently modified by IAA (iap1, GenBank accession no. ) was isolated and cloned from bush bean (...

BACKGROUND More than one billion human adults worldwide are overweight and, therefore, are at higher risk of developing cardiovascular diseases, diabetes, and a variety of other chronic perturbations. Many believe that use of natural dietary supplements could aid in the struggle against obesity. So-called "starch blockers" are listed among natural weight loss supplements. Theoretically, they ma...

Myo-Inositol Phosphate Synthase (MIPS; EC 5.5.1.4) catalyses the first committed step in inositol biosynthesis. The enzyme converts D-glucose 6-phosphate, an intermediate of the glycolytic pathway, to myo-inositol phosphate (Ins phosphate), which is subsequently converted to myo-inositol by the action of inositol monophosphatase [3]. It has been demonstrated that MIPS is a key enzyme during the...

This study focuses on lead detoxification using roots, stems, leaves and whole plants of Plantago major L. and Phaseolus vulgaris L. (decoration kidney bean) as a ball hanging hydroponically in deionized water supplemented with concentrations of lead ion under different duration times and temperatures regimes. Roots of studied plants showed that the highest removal of lead than other parts, whi...

The social and economic burden caused by chronic diseases such as obesity, diabetes, heart disease, and cancer is enormous. To reduce the impact of these diseases, we must find ways to reduce their prevalence. Epidemiological studies have found links between the incidence of cancer and consumption of dry edible bean {Phaseolus vulgaris L.) in the human diet. Correa (1981) examined data from 41 ...
