In this work, we present a new and fast Markov chain model (MCM) to predict the enzyme classification (EC) number.
Components are generally annotated with an appropriate type of identifier, e.g., an Entrez gene ID for genes and an Enzyme Classification (EC) number for enzymes.
The concept of generalized enzyme function is introduced and defined as the third-level enzyme function (EC i.j.k) according to the four-digit transformations of the enzyme classification system (EC i.j.k.l).l
Comparative analyses of protein electrostatic potentials and structural modeling are key tools for enzyme classification and characterization.
Enzyme classification codes and KEGG metabolic pathway annotations are generated from the direct mapping of GO terms to their enzyme code equivalents.
As a result, the ETA network diffusion method yields accurate predictions at the fourth, and highest resolution, level of the Enzyme Classification and also substantially reduces false positives compared to other annotation methods.
The standard enzyme classification scheme, for example, covers just over four thousand known enzyme functions (http://www.enzyme-database.org/stats.php) which depend upon a few thousand family-level structures (http://scop.mrc-lmb.cam.ac.uk/scop/count.html scop-1.71).html scop-1.71
Non-homologous ISofunctional Enzymes (NISE) is the preferred term to accurately describe enzymes that lack detectable sequence similarity but catalyze the same biochemical reactions and carry the same Enzyme Classification (EC) number [1].
Homology searches (BLASTX and BLASTN) of unique sequences and functional annotation by gene ontology terms (GO; www.geneontology.org), InterPro terms (InterProScan, EBI), enzyme classification codes (EC), and metabolic pathways (KEGG, Kyoto Encyclopedia of Genes and Genomes) were determined using the Blast2GO software suite v2.4.2 (www.orgst2go.org) [34].
Enzyme Classification (EC) analysis of the P. ulmi transcriptome.
KEGG maps and an enzyme classification number (EC number) were built for pathway analysis.
