Functional Family Acetylene hydratase

Enzyme Information

4.2.1.112
Acetylene hydratase.
based on mapping to UniProt Q71EW5
Acetaldehyde = acetylene + H(2)O.
-!- The tungsten center binds a water molecule that is activated by an adjacent aspartate residue, enabling it to attack acetylene bound in a distinct hydrophobic pocket. -!- Ethylene cannot act as a substrate.
