phosphatase/glycine max

A series of polyprenols, ranging in length from 15 to 22 isoprene units, has been isolated from soya beans (Glycine max) and purified by high-pressure liquid chromatography. N.m.r., i.r. and mass spectra of the compounds indicated that they are alpha-saturated polyprenols of the dolichol type. The

CONCLUSIONS GmPAP4 , a novel plant PAP gene in soybean, has phytase activity. Over-expressing GmPAP4 can enhance Arabidopsis growth when phytate is the sole P source in culture. Phosphorus (P) is an important macronutrient for plant growth and development. However, most of the total P in soils is

In this work we examined the effect of urea and guanidinium chloride on the structural stability of a single isoform of soybean seed acid phosphatase, based on the intensity of tryptophan fluorescence as a function of denaturant concentration. The free energy of unfolding, DeltaGu, was calculated at

In this paper, we describe a study concerning the determination of some characteristics of soybean seedlings and the detection of acid phosphatase activities towards different substrates during the germination. Enzyme activities with p-nitrophenylphosphate (pNPP) and inorganic pyrophosphate (PPi) as

The four soybean seed acid phosphatase isoforms AP1, AP2, AP3A and AP3B were competitively inhibited by phosphate, vanadate, fluoride and molybdate, using p-nitrophenylphosphate as substrate. The four isoforms were not significantly affected by compounds that can interact with SH residues or by

A phosphate-hydrolyzing activity from Glycine max embryo axes was purified by a series of chromatographic steps and electroelution from activity gels, and demonstrated to be an inositol-1 (or 4)-monophosphatase by partial internal amino acid sequence. This enzyme hydrolyzed ATP, sodium pyrophosphate

Plant protein tyrosine phosphatases (PTPs) are important in regulating cellular responses to redox change through their reversible inactivation under oxidative conditions. Studies on the soybean (Glycine max) GmPTP have shown that, compared with its mammalian counterparts, the plant enzyme is

Soybean [Glycine max (L.) Merr.] contains two proteins called vegetative storage proteins (VSPs) that function as temporary storage reserves, but are also closely related to plant acid phosphatases of the haloacid dehalogenase (HAD) superfamily. This study examined the biochemical basis for the

Phosphoglycolate phosphatase was partially purified from leaves of Nicotiana rustica using ion exchange and chromatofocusing columns. The native molecular weight of the enzyme was determined to be about 58 kD from Ferguson plots, with a subunit size of about 32 kD. The native enzyme is thus likely

Fruit removal for 5 weeks after flowering increased acid phosphatase activity 10-fold in soybean (Glycine max L. Merr. Var Hobbit) leaves compared with normal seed-pod-bearing plants. The major acid phosphatase activity in leaves was purified over 2700-fold, yielding a single polypeptide of 51 kD

We incorporated extract of Glycine max Merrill (GM), which is generally known as soybean, into a layered double hydroxide (LDH) nanostructure through two different methods, ion-exchange and reconstruction. Through X-ray diffraction, field-emission scanning electron microscopy, and

Bradyrhizobium japonicum mutant 132 was obtained by random TnphoA mutagenesis of strain 110spc4. A 6.5 kb BamHI kanamycin-resistance-coding DNA fragment of mutant 132 was used as a hybridization probe to clone the corresponding wild-type fragment. DNA sequence analysis of a 3213 bp BamHI-ClaI

Acid phosphatases are ubiquitous enzymes that exhibit activity against a variety of substrates in vitro, although little is known about their intracellular function. In this study, we report the isolation, characterization, and partial sequence of the major acid phosphatase from soybean (Glycine max

Three different organic-phosphorus-mineralizing bacteria (OPMB) strains were inoculated to soil planted with soybean (Glycine max), and their effects on soybean growth and indigenous bacterial community diversity were investigated. Inoculation with Pseudomonas fluorescens Z4-1 and Brevibacillus agri

We purified and partially sequenced a purple (lambda(max) = 556 nanometers) acid phosphatase (APase; EC 3.1.3.2) secreted by soybean (Glycine max) suspension-culture cells. The enzyme is a metalloprotein with a Mn(2+) cofactor. This APase appears to be a glycoprotein with a monomer subunit molecular
