Research ArticleOpen accessIn the abstractThe NifX Protein is Involved in the Final Stages of FeMo-cofactor Transport to the MoFe ProteinSurobhi Lahiri, Byron Cole, Lakshmi Pulakat, Nara GaviniThe nitrogenase enzyme catalyzes the reduction of dinitrogen to ammonia and is composed of the Fe and MoFe proteins. The iron molybdenum cofactor (FeMo-co) of the MoFe protein is the site of active substrate reduction. The NifX protein has also been suggested to have a role in the FeMo-co synthesis, although its exact role is still open to investigation. We … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 7,262 accessesView PDFCite
Research ArticleOpen accessIn the abstractTetrastigma hemsleyanum Diels et Gilg Roots from Different Origins: Pharmacognostical Identification, Content Determination of Functional Composition and in vitro Antioxidant ActivityGuang Mei Li, Jian Ge, Yongli Zheng et al.Tetrastigma hemsleyanum Diels et Gilg (T. hemsleyanum) is a unique and rare Chinese medicinal herb mainly distributed in the south of the Yangtze River in China. In the present study, T. hemsleyanum roots from seven different sites in the south of the Yangtze River (Guangxi [Baise, Guilin, and Hechi], Hunan [Fenghuang], and Zhejiang [Hangzhou, Taizhou, and Wenzhou] provinces) were collected, … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 1 · 23 Feb 2023 · 5,722 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Slum Water on Physiology of Heteropneustes fossilis Collected from Silchar, AssamRubina Roy, Bijoy Brahma, Satabdi Bhattacharjee, Soumitra NathPoverty and overpopulation are not just prevailing in big cities, but have also become a matter of concern in small towns. Safe drinking water is considered a basic human need, yet millions of people do not have access to an adequate and safe water supply. The present study is focused on the quality assessment of water bodies of slum areas … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 1 · 11 Feb 2019 · 7,912 accessesView PDFCite
Research ArticleOpen accessIn the abstractLocalization of the Dissimilatory Arsenate Reductase in Sulfurospirillum Barnesii Strain SeS-3Eman AfkarProblem statement: Sulfurospirillim barnesii strain SeS-3 is one of the recently known bacterial isolates that can obtain energy to support growth by respiring the toxic oxyanions of arsenic and selenium under anaerobic conditions. Approach: The ultimate goal of this investigation is to localize the active sites for the reduction of arsenate arsenite as well as selenate selenite in S. barnesii … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 5 Mar 2012 · 7,908 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Body Calming and Body Vitalizing Effects of Vernonia Amygdalina Leaf Extract and Leaf Powder and their MechanismsUtoh-Nedosa Uchechukwu AnastasiaProblem statement: Vernonia amygdalina (V. amygdalina) leaf soup is regarded by the indigenous Igbo people of South Eastern Nigeria as their best leafy vegetable soup. Despite the bitterness of the bitter leaf soup, the native eaters of the soup feel very content when they eat pounded carbohydrate foods with it. Oral V. amygdalina leaf extract was taken methodically in this … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 20 Sep 2011 · 8,163 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenomic Distance between Thymidylate Synthase and Dihydrofolate Reductase Genes Does Not Correlate With Phylogenetic Evolution in BacteriaVitor Hugo MoreauProblem statement: Dihydrofolate Reductase (DHFR) and Thymidylate Synthase (TS) exist as bifunctional enzymes coded into unique polypeptide chain in protozoans. Bifunctional DHFR-TS is associated with an increase in the enzymatic activity by channeling the substrate between the active sites. In some bacteria, DHFR and TS genes are neighbors in the genome, whereas in others, they are located millions of base … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 1 · 31 Mar 2010 · 8,188 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordIntegration of Electrical and Electromagnetic Investigation for Contaminated SiteAlberto Godio, Mario NaldiProblem statement: The environmental assessment of industrial areas is required to minimize the risk of soil and groundwater contamination. The survey of wide areas (e.g., some hectares) provides a high economical and complex logistical impact when random strategies of soil sampling are adopted. Recently, geophysical methods had been successfully adopted to drive the process of the spatial sampling of the … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,163 accessesView PDFCite
