Comparison with established databases showed that 25% of our domain set could not be deduced from SwissProt and 41% could not be annotated by Pfam, SMART is able to determine the modular architectures of single sequences or genomes application to the entire yeast genome revealed that at least 6.7% of its genes contain one or more signaling domains, approximately 350 greater than previously annotated. The majority of signaling proteins are multidomain in character with a considerable variety of domain combinations known. 2.Īccurate multiple alignments of 86 domains that occur in signaling proteins have been constructed and used to provide a Web based tool (SMART: simple modular architecture research tool) that allows rapid identification and annotation of signaling domain sequences. All links to services or download sites are given in the text or listed in Table 1 the succession of tools is briefly summarized in Fig. Regarding a gene, protein, structure, or interaction of interest by applying current publicly available software and databases In this chapter, we will provide a guide for the most efficient way to analyze a given sequence or to collect information The problem of which to use and how best to obtain scientifically valid answers (3). The large number of bioinformatic tools that have been made available to scientists during the last few years has presented In addition, a set of methods for protein analysis summarized under the term proteomics holds tremendous potential for biomedicine and biotechnology (141). Of genome-sequence analysis will include the understanding of diseases, gene regulation, and metabolic pathway reconstruction. This is an important task, considering that even in the best studied bacterium Escherichia coli more than 30‰ of the identified open reading frames (ORFs) represent hypothetical genes with no known function. Development of bioinformatic tools has evolved rapidly in order to identify genes thatĮncode functional proteins or RNA. Analysis of this overwhelming amount of data, including hundreds of genomes from both prokaryotes and eukaryotes, has given An enormous amount of DNA sequence data are available and databases still grow exponentially (seeįig. In the determination of the entire human genome in 2001 (1,2). The rapid development of efficient, automated DNA-sequencing methods has strongly advanced the genome-sequencing era, culminating
