The names corresponds to the manufacturer identifiers. If this information is unknown, the vector will contain an \code{NA}. For the @ANNOBJPREFIX@ENZYME2PROBE, each EC number maps to a named vector containing all of the manufacturer identifiers that correspond to the gene that produces that enzyme. The name of the vector corresponds to the EC number. Enzyme Commission numbers are assigned by the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology \url{http://www.chem.qmw.ac.uk/iubmb/enzyme/} to allow enzymes to be identified. An Enzyme Commission number is of the format EC x.y.z.w, where x, y, z, and w are numeric numbers. In @ANNOBJPREFIX@ENZYME2PROBE, EC is dropped from the Enzyme Commission numbers. Enzyme Commission numbers have corresponding names that describe the functions of enzymes in such a way that EC x is a more general description than EC x.y that in turn is a more general description than EC x.y.z. The top level EC numbers and names are listed below: EC 1 oxidoreductases EC 2 transferases EC 3 hydrolases EC 4 lyases EC 5 isomerases EC 6 ligases The EC name for a given EC number can be viewed at \url{http://www.chem.qmul.ac.uk/iupac/jcbn/index.html#6} Mappings between probe identifiers and enzyme identifiers were obtained using files provided by: @ENZYMESOURCE@ } \references{ \url{ftp://ftp.genome.ad.jp/pub/kegg/pathways} } \seealso{ \itemize{ \item \code{\link[AnnotationDbi]{AnnotationDb-class}} for use of the \code{select()} interface. } } \examples{ ## select() interface: ## Objects in this package can be accessed using the select() interface ## from the AnnotationDbi package.
