Proceedings of the 3rd International Beilstein Workshop on Experimental Standard Conditions of Enzyme Characterizations

The almost complete sequencing of the genomes from numerous organisms paved the way for the development and application of new experimental and instrumental techniques which contribute to the understanding of complex biological pathways and networks by providing apparently endless opportunities to generate massive amounts of data. Cell machinery is currently envisaged as an inter-relationship of enzymes, proteins and chemical compounds. However, both a large number of metabolic pathways and enzymes even in well-described pathways still remain unknown. It is therefore necessary to develop further experimental and mathematical methods to reconstruct unknown parts of the networks, to identify genes for missing enzymes and to characterize the kinetic behaviour of those enzymes that have been identified. The post-genomic era is also characterized by the concept of systems biology. This has gained significant momentum and metabolic research is now being conducted on an integrated and cross-disciplinary platform pulling together its resources from diverse fields such as mathematics, computational biology, bioinformatics, functional genomics and proteomics, and structural biology. The enormous growth in the computation speed and data storage capability has fuelled new opportunities for both the accumulation of massive amounts of sequence, expression and functional data and the characterization, analysis and comparison of larger biological systems. However, as long as the data quality of the in-put and the resulting modelling data cannot be improved, the chances of success for this young discipline to escape from the verbally overused ?omics-sciences are poor. Systems level investigation of genomic and proteomic scale information requires incomparably higher demands for data quality than in previous decades. Truly integrated databases that deal with heterogeneous data need to be developed to be able to retrieve properties of genes, for kinetics of enzymes, for behaviour of complex networks and for the analysis and modelling of complex biological processes. One perspective of the output can be the investigation of cellular pathways involved in disease biology and targeted by newer molecular therapeutics. The understanding of these processes will assist the development of early diagnosis, prognosis and the prediction of response to individual therapies. Despite the fast paced global efforts in biological systems research, the current analyses are limited by the lack of available systematic collections of comparable functional enzyme data. Besides its reliability, these data have to provide defined minimum experimental information, they must be available from the literature along with their accepted enzyme names, and must be as comprehensive as possible.
