The aim of the Natural Sciences Bibliographic Web Portal including its new Polymerase and Reductase Bibliography is to provide comprehensive scholarly information on the basic and applied life, earth and health sciences. While the publishers target to publish a total of over 8.7 million references until 2014, the site currently publishes about 5,000 new items every day. Every reference consists of basic bibliographic information and the summary of the publication's scientific content. Furthermore, each reference is tagged with up to twenty scientific keywords.
The Natural Sciences Enzyme Bibliography Section contains scientific information on enzymes, which are biological molecules that living organisms produce in order to catalyze and thereby increase the speed or rates of specific biochemical reactions. The substrates, which are what molecules are called at the beginning of the enzymatic reaction, are converted into different molecules, known as products. Almost every chemical reaction that occurs in a biological cell requires enzymes for performing at a rate that is sufficient for sustaining life. The latest content in this category is also available through an Natural Sciences Enzyme Bibliography RSS feed. The section currently contains almost 8,000 posts and is subdivided into the ten categories Dehydrogenase, Electrophoresis, Escherichia, Immunosorbent, Kinase, Oxidase, Peptide, Peroxidase, Polymerase, and Reductase.
Within this section, the new category Polymerase contains scientific information on this enzyme which is associated with polymers of nucleic acids such as the deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The main function of a polymerase is to polymerize new DNA or RNA against a currently existing DNA or RNA template. Polymerases also take nucleotides from solvent and bring about the synthesis of polynucleotide sequences. The category contains over 230 newly published posts of which the very latest inclusions are also available through a Polymerase RSS feed. It features posts on diagnosis of flame chlorosis by reverse transcription-polymerase chain reaction (RT-PCR), detection of soluble methane monooxygenase producing Methylosinus trichosporium OB3b by polymerase chain reaction, and on controlled expression of plastid transgenes in plants based on a nuclear DNA-encoded and plastid-targeted T7 RNA polymerase.
The new category Reductase contains scientific information on this enzyme that is known for catalyzing reduction and reduction oxidation reactions in various kinds of proteins. A reductase is an enzyme that brings about or catalyzes a reduction reaction, which is also known as a "redox" (reduction oxidation) reaction. There are many kinds of reductase, such as the dihydrofolate reductase, an enzyme that produces a reduction reaction in dihydrofolic acid by using the NADPH as an electron donor. Another kind of reductase is the HMG-CoA reductase, which is an enzyme that controls the rate of the mevalonate pathway which is known for producing cholesterol and other kinds of isoprenoids. This category contains over 500 newly published posts of which the very latest inclusions are also available through a Reductase RSS feed. It features posts on developmental regulation of Trypanosoma brucei cytochrome C reductase during bloodstream to procyclic differentiation, on constitutive variation of ascorbate peroxidase activity during development parallels that of superoxide dismutase and glutathione reductase in paraquat-resistant Conyza, and on vo-expression of native and introduced genes reveals cryptic regulation of HMG CoA reductase expression in Arabidopsis.
While the publishers of the web portal have a stock of 8,659,374 references this information will be made successively available to the public until 2014. While the site has presently published a total of 184,821 posts online, the number of published bibliographic resources increases by about 5,000 items every day. All items are interconnected with 133,656 scientific tags. The publishing status is reflected in the site's continuously updated tagline.
