intramolecular oxidoreductase activity, interconverting keto- and enol-groups

intramolecular isomerase activity, interconverting keto- and enol-groups

proteasome core complex (sensu Eukaryota)

A multisubunit barrel shaped endoprotease complex, which is the core of the proteasome complex. This complex is involved in the proteolysis of substrates in an ATP dependent manner and consists of four ring-like structures, two outer and two inner, each containing seven subunits. As in, but not restricted to, the eukaryotes (Eukaryota, ncbi_taxonomy_id:2759).

intramolecular oxidoreductase activity, transposing S-S bonds

intramolecular isomerase activity, transposing S-S bonds

intramolecular transferase activity, transferring other groups

Catalysis of the transfer of a functional group from one position to another within a single molecule.

intramolecular transferase activity, transferring acyl groups

Catalysis of the transfer of an acyl group from one position to another within a single molecule.

Catalysis of the transfer of a phosphate group from one position to another within a single molecule.

Catalysis of the geometric or structural changes within one molecule. Isomerase is the systematic name for any enzyme of EC class 5.

racemase and epimerase activity, acting on other compounds

Catalysis of a reaction that alters the configuration of one or more chiral centers in a molecule.

racemase and epimerase activity, acting on amino acids and derivatives

Catalysis of a reaction that alters the configuration of one or more chiral centers in an amino acid.

racemase and epimerase activity, acting on carbohydrates and derivatives

Catalysis of a reaction that alters the configuration of one or more chiral centers in a carbohydrate molecule.

Catalysis of a reaction that interconverts cis and trans isomers. Atoms or groups are termed cis or trans to one another when they lie respectively on the same or on opposite sides of a reference plane identifiable as common among stereoisomers.
