The concentrations of free amino acids and amides within isolated maize (Zea mays L.) plastids were determined and compared with concentrations in the leaf tissue. The concentrations were different for each individual amino acid and varied between 1 and 10 millimolar. At five different developmental
When sperm-positive female rats were treated with freshly prepared formulations of [D-Trp6, des-Gly10]-LHRH ethyl amide (LRA) in corn oil, the effects on pregnancy occurred in a dose-related manner. When the same formulation was retested after five-and-a-half years of storage under refrigeration,
When corn seedlings, previously depleted in soluble nitrogen constituents, are forced to absorb large quantities of ammonium nitrogen, soluble compounds accumulate in the sap. Asparagine, glutamine, one or more amino acids and undetermined compounds are synthesized. Ammonia does not accumulate until
The pharmacokinetics of 3-(decyldimethylsilyl)-N-[2-(4-methylphenyl)-1-phenylethyl]propanamide (DMPP), an inhibitor of acyl-CoA:cholesterol acyltransferase, have been studied in the dog and the rat using 14C and 3H dual-labelled drug. In both species, gastrointestinal absorption of DMPP was slow and
The pool of amide-linked indole-3-acetic acid (amide IAA) in the shoot of growing etiolated seedlings of Zea mays increases between the 3rd and 5th day of germination to equal the amount of free IAA and two-thirds the amount of ester IAA. Deseeding the germinant changes the pool size of free and
To investigate nitrogen assimilation and translocation in Zea mays L. colonized by the vesicular-arbuscular mycorrhizal (VAM) fungus Glomus fasciculatum (Thax. sensu Gerd.), we measured key enzyme activities, 15N incorporation into free amino acids, and 15N translocation from roots to shoots.
BACKGROUND
Transglutaminases catalyze post-translational modification of proteins by ε-(γ-glutamyl) links and covalent amide bonds. Research on properties and applications of plant transglutaminases is less developed than in animals and micro-organisms. In a previous study, optimized Zea mays
Purification and collection of industrial products from oil-water mixtures are commonly implemented processes. However, the efficiencies of such processes can be severely influenced by the presence of emulsifiers that induce formation of small oil droplets dispersed in the mixtures. Understanding of
Transglutaminases (TGases) catalyze post-translational protein modifications by ε-(γ-glutamyl) links and covalent amide bonds. In plant, this enzyme is poorly studied and only the Zea mays TGase gene (tgz) has been cloned. The tgz had been expressed in Escherichia coli, but the recombinant protein
Bolaform amides were designed from N,N'-bis(carboethoxy-L-valinyl)-diaminoethane (1) by linking t-butyloxycarbonyl-valine through ethylenediamine (EDA) to enable spectroscopic and X-ray diffraction analyses. N,N'-Bis(Boc-L-valinyl)-diaminoethane (2) and N,N'-bis(Boc-D-valinyl)-diaminoethane (3) were
Advancement in materials synthesis largely depends up on their diverse applications and commercialisation. Antifungal effects of phytogenic silver nanoparticles (AgNPs) were evident, but the reports on the effects of the same on agricultural crops are scant. Herein, we report for the first time,
An enrichment culture technique was used for the isolation of bacteria capable of utilizing fipronil as a sole source of carbon and energy. Based on morphological, biochemical characteristics and phylogenetic analysis of 16S rRNA sequence, the bacterial strains were identified as Acinetobacter
Mycobacteria remain an important problem worldwide, especially drug resistant human pathogens. Novel therapeutics are urgently needed to tackle both drug-resistant tuberculosis (TB) and difficult-to-treat infections with nontuberculous mycobacteria (NTM). Benzothiazole adamantyl amide had previously
Fipronil is a widely used insecticide in agriculture and can cause potential health hazards to non-target soil invertebrates and nearby aquatic systems. In the present study, a fipronil degrading bacterium was isolated from fipronil contaminated soil, i.e. rhizospheric zone of Zea mays.
