Proteomics & metabolomics: Mapping biochemical regulations

Large-scale studies in the field of omics have been successfully exploring the differences in gene expression, protein and metabolite abundance and modification of post-translational protein, and providing a different level of views for the cellular processes occur in cells. Proteomics and metabolomics are new addition to the ‘omics’ field, but both of them are still developing its own computational infrastructure by assessing the computational needs of its own. Due to the strong knowledge on chemical information and the importance of linking this chemical information to biological consequences, proteomics and metabolomics combines the elements of traditional bioinformatics and cheminformatics.
