Targeted to 400,000 life science researchers worldwide, the company\\\'s web site provides free, easy-to-use analytical tools and scientist-authored reviews of high-end, experiment-specific research products, such as enzymes, antibodies and reagent kits.
• BRENDA: enzyme database: BRENDA is the main collection of enzyme functional data available to the scientific community. It is available free of charge for via the internet (www.brenda-enzymes.org).
• DNA ligation protocol: DNA ligation is the process of joining together two DNA molecule ends (either from the same or different molecules). Specifically, it involves creating a phosphodiester bond bond between the 3\' hydroxyl of one nucleotide and the 5\' phosphate of another. This reaction is usually catalyzed by a DNA ligase enzyme. This enzyme will ligate DNA fragments having blunt or overhanging, complementary, \'sticky\' ends. Typically, it is easier to ligate molecules with complementary sticky ends than blunt ends. T4 DNA ligase is the most commonly used DNA ligase for molecular biology techniques and can ligate \'sticky\' or blunt ends.
• Enzymatic RNA Molecules and the Replication of Chromosome Ends: A cell must orchestrate thousands of chemical reactions in order to live, to grow, and to respond to its environment. These chemical reactions rarely happen spontaneously but are usually catalyzed by macromolecules called enzymes. It was long thought that all enzymes were proteins. More recently we and others have found that RNA can in some cases act as an enzyme.
• Identifying mutations in genes encoding insecticide target proteins: We have played a leading role in identifying mutations in the insect voltage-gated sodium channel and the enzyme acetylcholinesterase (AChE) which confer resistance to pyrethroids and organophophate/carbamate insecticides respectively. This is leading to an increased fundamental understanding of how these insect nervous system proteins function and ideas for better/new pest management strategies.
• Introduction to Protein Structure: This project develops, tests and incorporates into introductory chemistry and biology courses a series of modules based on important scientific themes: molecular aspects of biological structures, bonding and intermolecular forces, dynamics including enzymes and catalysis, aspects of equilibria especially acids and bases, energy and thermodynamics, organic reaction mechanisms especially metabolism, and bioethics.
• One Gene - One Enzyme Theory: This led them to postulate the one gene - one enzyme theory: each gene in an organism controls the production of a specific enzyme. It is these enzymes that catalyze the reactions that lead to the phenotype of the organism. Today, we know that, in fact, not only enzymes, but all the other proteins from which the organism is built are encoded by genes.
• RESearch - a new computer program for DNA analysis: The main design philosophy behind the development of RESearch was to make the basic DNA analysis tools readily available on IBM PCs, and to make them easy to use. RESearch enables molecular biologists to analyse a GCG formatted sequence in several ways including searching for short nucleotide sequences and restriction enzyme sites, translating open reading frames and searching for short amino acid sequences.
• SeqSearch: SeqSearch is build around a collection of databases for restriction enzymes, DNA sequences, plasmids, contructs, oligo's and motifs and offers an extended set of editing and analysis tools.
• UGENE - Unipro: UGENE is a free cross-platform genome analysis suite. Multiple sequence alignment using MUSCLE 3,4 and KAlign; HMM profiles build and search, based on the source of HMMER 2 and HMMER 3; PCR Primers design using Primer 3; Protein secondary structure prediction using GOR IV and PSIPRED; Phylogenetic analysis with Phylip; Search for restriction enzymes and integration with REBASE; Extremely fast repeat finder; DNA reference assembly using Bowtie; Search for transcription factor binding sites using SITECON; Protein back translation; ORF finder; Complete Smith-Waterman algorithm implementation; Comparing genomes using dotplot view.
