ENZYME entry: EC 3.1.1.2
| Accepted Name |
|---|
| Arylesterase.
|
| Alternative Name(s) |
|---|
| A-esterase. |
| Paraoxonase. |
| Reaction catalysed |
|---|
| A phenyl acetate + H(2)O <=> a phenol + acetate |
| Comment(s) |
|---|
- Acts on many phenolic esters.
- It is likely that the three forms of human paraoxonase are lactonases
rather than aromatic esterases.
- The natural substrates of the paraoxonases are lactones, with (+-)-5-
hydroxy-6E,8Z,11Z,4Z-eicostetraenoic-acid 1,5-lactone being the best
substrate.
