| active site |
活性部位, That portion of a protein, usually an enzyme, whose structural integrity is required for function (eg, the substrate binding site of an enzyme). Enzymes may have more than one active site and so catalyse more than one reaction. Competitive inhibitors of an enzyme reaction bind reveribly to the active site and reduce its availability for normal substrate.
