This paper evaluates the intakes of the trace elements: iron, zinc and selenium as obtained from food consumption calculations based on the most recent data of JHEIS, 2006. The estimated mineral intake was analyzed using a nutrition analysis software program (Food Processor SQL, 2008). The nutrient intake of these 3 trace elements for different governorates was calculated. The results showed th...

Site-directed mutagenesis and X-ray absorption spectroscopy studies have previously shown that the tRNA-guanine transglycosylase (TGT) from Escherichia coli is a zinc metalloprotein and identified the enzymic ligands to the zinc [Chong et al. (1995), Biochemistry 34, 3694-3701; Garcia et al. (1966), Biochemistry 35, 3133-3139]. During these studies one mutant, TGT (C265A), was found to exhibit ...

The term motif is used in two different ways in structural biology. The first refers to a particular amino-acid sequence that is characteristic of a specific biochemical function. An example is the so-called zinc finger motif, CXX(XX)CXXXXXXXXXXXXHXXXH, which is found in a widely varying family of DNA-binding proteins (Figure 1-49). The conserved cysteine and histidine residues in this sequence...

Currently, commercializing the Piriformospora indica fungal formulation using magnesium sulphite as a carrier with the registered trade name “Rootonic”. It enhances the plant growth, biotic and abiotic stress tolerance and also increases the accessibility of nutrients to plants. Biotic stress and nutritional deficiency i.e. zinc in soil are the two important factor for the deteriotion of grain ...

The human immunodeficiency virus type 1 (HIV-1) nucleocapsid (NC) protein contains 15 basic residues located throughout its 55-amino acid sequence, as well as one aromatic residue in each of its two CCHC-type zinc finger motifs. NC facilitates nucleic acid (NA) rearrangements via its chaperone activity, but the structural basis for this activity and its consequences in vivo are not completely u...

introduction integrated nutrient management involving crop residue/green manures and chemical fertilizer is potential alternative to provide a balanced supply of nutrients, enhance soil quality and thereby sustain higher productivity. the present experiment was undertaken to evaluate the effect of different crop residue management practices and npk levels on yield components and yield of wheat....

Abstract Plant residues are often used as soil amendments in laboratory experiments, but they can reportedly release compounds interfering with DNA extraction and subsequent molecular biological analyses. Theoretically, for accurate comparison of microbial community composition soils without added plant after a period incubation, no significant difference at the beginning experiment is required...

crop residues management is one of the most important factors to sustain agro-ecosystems. application of plant residues as organic fertilizers has functional role on the amount of soil elements, their availability for crops and finally yield obtained. in order to investigate the effect of different crop residues and their management on providing wheat potassium requirement, a four-replicated fi...
