It is generally believed that Chl and bacteriochlorophyll biosynthesis are evolutionarily related. This supposition is supported by the observation that the biosynthetic pathway for Chl a involves intermediates that are common with bacteriochlorophyll a biosynthesis (reviewed in ref. 7) and by the observation that light-independent reduction of protochlorophyllide to Chlide involves an enzyme c...

Abstract Cancer development is a complicated process controlled by the interplay of multiple signaling pathways and restrained oxygen nutrient accessibility in tumor microenvironment. High plasticity using diverse nutrients to adapt metabolic stress one hallmarks cancer cells. To respond meet requirements for rapid cell proliferation, cells reprogram take up more glucose coordinate production e...

to identify the larvicidal activities of silver nanoparticles synthesized with acanthus ilicifolius (a. ilicifolius) leaf extract against the larvae of armigeressubalbatus and aedesaegypti. in vitro larvicidal activities such as lc50 and lc90 were assessed for the a. subalbatus  and ae.aegypti larval species. further, characterization using different techniques such as uv, sem,edax, xrd and fti...

a facile and green approach has been developed to synthesize silver nanoparticle (ag-nps). this was carried out by a biosynthetic route using justicia adhatoda root extract as reducing and stabilizing agent. the structure, composition, average particle size (~25 nm) and surface morphology of ag-nps were characterized by the x-ray diffraction, transmission electron microscope and atomic force mi...

The trafficking of Src family proteins after biosynthesis is poorly defined. Here we studied the role of dual fatty acylation with myristate and palmitate in biosynthetic transport of p59fyn. Metabolic labeling of transfected COS or NIH 3T3 cells with [35S]methionine followed by analysis of cytosolic and total membrane fractions showed that Fyn became membrane bound within 5 min after biosynthe...

Recent developments in synthetic biology have positioned lactic acid bacteria (LAB) as a major class of cellular chassis for applications. To achieve the full potential of LAB, one fundamental prerequisite is the capacity for rapid engineering of complex gene networks, such as natural biosynthetic pathways and multicomponent synthetic circuits, into which cellular functions are encoded. Here, w...

background and objectives: food contamination by aflatoxins is an important food safety concern for agricultural products. in order to identify and develop novel antifungal agents, several plant extracts and isolated compounds have been evaluated for their bioactivities. anti-infectious activity of piper betle used in traditional medicine of malaysia has been reported previously. materials and ...

The current study emphasizes the process of synthesis of nanoparticles from the natural residue that is rapid and eco-friendly. So we present a simple and eco-friendly biosynthesis of silver nanoparticles using Ficus benghalensis fruit extract as reducing agent, rapid reduction of silver ions is observed leading to the formation of silver nanoparticles in solution. The synthesized nanoparticles...

background: sustainable and commercial production of taxol as an anti cancer drug is a critical point to its clinical application. nowadays, hazel because of rapid growth and wide range distribution is considered as an alternative source of taxol. objective: to increase taxol production the cdna encoding 3-hydroxy-3-methylglutaryl-coa reductase (hmgr) from iranian hazel (genebank accession numb...
