The Enzyme Database

Table of Contents

The enzymes in this section of the database are organized as you would find them in the Enzyme-Nomenclature book. Click [+] to expand, and [–] to collapse, any section. Clicking on a heading will open popup window with information on that class, subclass or sub-subclass.

    EC 1.1  [+]      
    EC 1.2  [+]      
    EC 1.3  [+]      
    EC 1.4  []      
        EC 1.4.1       [+]    With NAD+ or NADP+ as acceptor 
        EC 1.4.2       [+]    With a cytochrome as acceptor 
        EC 1.4.3       []    With oxygen as acceptor 
                EC 1.4.3.1                      D-aspartate oxidase 
                EC 1.4.3.2                      L-amino-acid oxidase 
                EC 1.4.3.3                      D-amino-acid oxidase 
                EC 1.4.3.4                      monoamine oxidase 
                EC 1.4.3.5                      pyridoxal 5′-phosphate synthase 
                EC 1.4.3.6                      amine oxidase (copper-containing). This was classified on the basis of cofactor content rather than reaction catalysed and is now known to contain two distinct enzyme activities. It has been replaced by two enzymes, EC 1.4.3.21 (primary-amine oxidase) and EC 1.4.3.22 (diamine oxidase) 
                EC 1.4.3.7                      D-glutamate oxidase 
                EC 1.4.3.8                      ethanolamine oxidase 
                EC 1.4.3.9                       tyramine oxidase. Now included with EC 1.4.3.4 amine oxidase (flavin-containing) 
                EC 1.4.3.10                      putrescine oxidase 
                EC 1.4.3.11                      L-glutamate oxidase 
                EC 1.4.3.12                      cyclohexylamine oxidase 
                EC 1.4.3.13                      protein-lysine 6-oxidase 
                EC 1.4.3.14                      L-lysine oxidase 
                EC 1.4.3.15                      D-glutamate(D-aspartate) oxidase 
                EC 1.4.3.16                      L-aspartate oxidase 
                EC 1.4.3.17                      tryptophan α,β-oxidase. Now EC 1.3.3.10, tryptophan α,β-oxidase. Enzyme was incorrectly classified as acting on a CH-NH bond rather than a CH-CH bond 
                EC 1.4.3.18                      cytokinin oxidase. Not approved as the enzyme was shown to be a dehydrogenase and not an oxidase (see EC 1.5.99.12, cytokinin dehydrogenase) 
                EC 1.4.3.19                      glycine oxidase 
                EC 1.4.3.20                      L-lysine 6-oxidase 
                EC 1.4.3.21                      primary-amine oxidase 
                EC 1.4.3.22                      diamine oxidase 
                EC 1.4.3.23                      7-chloro-L-tryptophan oxidase 
                EC 1.4.3.24                      pseudooxynicotine oxidase 
                EC 1.4.3.25                      L-arginine oxidase 
        EC 1.4.4       [+]    With a disulfide as acceptor 
        EC 1.4.5       [+]    With a quinone or other compound as acceptor 
        EC 1.4.7       [+]    With an iron-sulfur protein as acceptor
