EC 1.7.3.2     
Accepted name: acetylindoxyl oxidase
Reaction: N-acetylindoxyl + O2 = N-acetylisatin + (?)
Systematic name: N-acetylindoxyl:oxygen oxidoreductase
Links to other databases: BRENDA, EXPASY, KEGG, MetaCyc, CAS registry number: 9029-37-2

EC 1.14.13.235     
Accepted name: indole-3-acetate monooxygenase
Reaction: (indol-3-yl)acetate + NADH + H+ + O2 = (2-hydroxy-1H-indol-3-yl)acetate + NAD+ + H2O
Glossary: (indol-3-yl)acetate =(1H-indol-3-yl)acetate = indole-3-acetate
Other name(s): iacA (gene name)
Systematic name: (indol-3-yl)acetate,NADH:oxygen oxidoreductase (2-hydroxylating)
Comments: The enzyme, characterized from Pseudomonas putida strains, catalyses the first step in a pathway for degradation of the plant hormone indole-3-acetate. When acting on indole, the enzyme forms indoxyl, which reacts spontaneously with oxygen to form the blue dye indigo.

EC 2.4.1.220     
Accepted name: indoxyl-UDPG glucosyltransferase
Reaction: UDP-glucose + indoxyl = UDP + indican
Glossary: indoxyl = indole-3-ol
Other name(s): indoxyl-UDPG-glucosyltransferase
Systematic name: UDP-glucose:indoxyl 3-O-β-D-glucosyltransferase
Comments: Also acts to a limited extent on 4-, 5-, 6- and 7-hydroxyindole. After enzymic or chemical hydrolysis, indican forms indoxyl, which, in turn, is converted in the presence of oxygen to the dye indigo.

EC 3.1.1.56     
Accepted name: methylumbelliferyl-acetate deacetylase
Reaction: 4-methylumbelliferyl acetate + H2O = 4-methylumbelliferone + acetate
Other name(s): esterase D
Systematic name: 4-methylumbelliferyl-acetate acylhydrolase
Comments: Acts on short-chain acyl esters of 4-methylumbelliferone, but not on naphthyl, indoxyl or thiocholine esters.
