Enzyme Information

3.7.1.17

4,5-9,10-diseco-3-hydroxy-5,9,17-trioxoandrosta-1(10),2-diene-4-oate hydrolase.

based on mapping to UniProt P9WNH5

(1E,2Z)-3-hydroxy-5,9,17-trioxo-4,5:9,10-disecoandrosta-1(10),2-dien-4- oate + H(2)O = 3-((3aS,4S,7aS)-7a-methyl-1,5-dioxo-octahydro-1H-inden-4- yl)propanoate + (2Z,4Z)-2-hydroxyhexa-2,4-dienoate.

-!- The enzyme is involved in the bacterial degradation of the steroid ring structure, and is involved in degradation of multiple steroids, such as testosterone, cholesterol, and sitosterol.

3.7.1.8

2,6-dioxo-6-phenylhexa-3-enoate hydrolase.

based on mapping to UniProt P9WNH5

2,6-dioxo-6-phenylhexa-3-enoate + H(2)O = benzoate + 2-oxopent-4-enoate.

-!- Cleaves the products from biphenol, 3-isopropylcatechol and 3-methylcatechol produced by EC 1.13.11.39 by ring-fission at a -CO-C bond. -!- Involved in the breakdown of biphenyl-related compounds by Pseudomonas sp.
