Genome analysis prediction

It should be possible to extend the DNA microarray-binding experiment to whole-genome analysis of transcription factor binding sites. The authors suggest that a microarray spotted with 12,000 one-kilobase sequences would span the entire Saccharomyces cerevisiae genome (Bulyk et al., 2001). Such an array could be used to characterize the sequence specificity of S. cerevisiae transcription factors. These experiments would be useful for predicting functions of previously uncharacterized transcription... 

Traditionally protein-protein interactions studies have been performed in vitro after isolation and purification of individual proteins. While some in vivo or in situ protein-protein interaction studies can be performed by traditional methods using microinjection of purified proteins into oocytes, technical complexities limit the number of proteins that can be studied. Furthermore, many putative proteins of interest, predicted by genomic analysis, are not characterized and cannot be used in such studies. Some of the limitations posed by traditional methods have been overcome by use of yeast two-hybrid systems. These systems allow studies of many recombinant test proteins...

Interpretation of results of these studies is still difficult. Results of two-hybrid methods become more useful if they can be coordinated with other approaches. For example, computational methods can predict interactions from genome sequences alone. 11/0 More than 45,000 interactions have been predicted among yeast proteins. Reliable identification of such motifs as DNA-binding domains and Ca2+- binding domains can complement two-hybrid analysis.11 The yeast genome is predicted to contain 162 coiled-coil sequences and at least 213 unique interactions between them.0 Examination of sequences of protein families in the Protein Data Bank (PDB) led to prediction of 8151 interactions of 664 types between protein families in yeast.P... 

According to genomic analysis, the numbers of predicted open reading frames in strains 26695, J99, and HPAG1 are 1,590, 1,495, and 1,536, respectively. Of these three strains, only HPAG1 has a plasmid, pHPAGl (17). 

In another example, comparative genome comparison was combined with constraints-based flux analysis to develop metabolic engineering strategies for the enhanced production of succinic acid by E. coli [1, 39, 40]. Comparative genome analysis of E. coli and M. succiniciproducens predicted five candidate genes to be manipulated for overproducing succinic acid in E. coli. Then, constraints-based flux...

Because the World Wide Web makes genome sequences available to anyone with Internet access, there exists a variety of databases that offer more or less convenient access to basically the same sequence data. However, several research groups, specializing in genome analysis, maintain databases that provide important additional information, such as operon organization, functional predictions, three-dimensional structure, and metabolic reconstructions.
