Tree Number(s): D08.811
Unique ID: D004798
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D004798
Annotation: general only: avoid; prefer specific enzyme or / enzymol: Manual 19.7+, 19.8.30; policy: Manual 25.18+; SUBSTRATE SPECIFICITY, restricted to enzymes, is available; ENZYME TESTS, CLINICAL is available for measuring the level of a specific enzyme in the diagnosis of a disease; ENZYME ACTIVATION; ENZYME REPRESSION; ENZYME STABILITY are also available; ENZYME INDUCTION: coordinate with specific enzyme / biosyn
