Use wild characters " ? " and " * " for efficient search:
  • ? : A single character. E.g., trehalose?phosphatase covers both trehalose phosphatase and trehalose-phosphatase, of which, only the latter fits the nomenclature used in this database.
  • * : Any number of characters. E.g.,tre-* brings all genes from trehalase family; coenzyme*A covers coenzyme A, coenzyme-A, and coenzymeA.

Reactions
ID Enzyme Reactants Products Genes (?) Multiple genes are separated by OR (I) or AND (&).

I indicates that genes are redundant within the group (e.g. paralogs encoding the same enzyme).
& indicates that genes are non-redundant within the group (e.g. genes encoding different subunits of the same enzyme).

If there are multiple groups of genes, as in an enzyme complex with some enzymes associated with multiple genes, or in a case where the same enzyme is associated with different orthology groups with paralogs, each group with multiple genes is shown in parentheses. 		Pathway
