Bray N, et al. MAVID: Constrained ancestral alignment of multiple sequences. [arXiv pre-print archive (http://arXiv.org/abs/q-bio/0311018)]: Describes a global multiple alignment program that incorporates maximum-likelihood inference of ancestral sequences; automatic guide-tree construction; protein-based anchoring of ab initio gene predictions; and constraints derived from a global homology map of the sequences. According to the authors, MAVID is able to accurately align multiple genomic regions up to several megabases long.
Claudel-Renard C, et al. Enzyme-specific profiles for genome annotation: PRIAM. [Nucleic Acids Research 31(22): 6633-6639]: Describes PRIAM (Profils pour l’Identification Automatique du Métabolisme), a method for automated enzyme detection and metabolic pathway reconstruction in fully sequenced genomes, based on the classification of enzymes in the Enzyme database.

Djordjevic M, et al. A biophysical approach to transcription factor binding site discovery. [Genome Research 13(11): 2381-90]: Discusses a bioinformatics method that classifies potential binding sites based on the estimate of sequence-specific binding energy of a given transcription factor. The method also estimates the chemical potential of the factor that defines the threshold of binding. According to the authors, the approach provides “a significant improvement in the number of expected false positives, particularly in the ubiquitous case of low-specificity factors.”

Matthiessen M. BioWareDB: the biomedical software and database search engine. [Bioinformatics 19(17): 2319-20]: Describes a catalog and search engine for bioinformatics software and databases, which currently “live a shadow existence compared to experimental results and methods that are widely published in journals and relatively easily found through publication databases such as PubMed,” according to the authors. BioWareDB currently contains 2,800 entries. Availability: http://www.biowaredb.org/.

Romualdi C, et al. Improved detection of differentially expressed genes in microarray experiments through multiple scanning and image integration. [Nucleic Acids Research 31(23) e149]: Describes software that creates a virtual image to integrate microarray images and statistically summarize a series of consecutive scans of a microarray. According to the authors, the increase in the final number of differentially expressed genes detected with this approach is 50 percent more for microarrays hybridized with targets labeled by reverse transcriptase, and 200 percent more for microarrays developed with the tyramide signal amplification technique.
Thareau T, et al. Automatic design of gene-specific sequence tags for genome-wide functional studies. [Bioinformatics 19(17): 2191-2198]: Describes SPADS (Specific Primer and Amplicon Design Software), which designs gene-specific sequence tags by comparing divergent regions in each gene with a completely annotated genome sequence and selecting optimal primer pairs for the PCR amplification of one divergent region per gene.
