Enzymatic reaction of: lactonase

D-galactono-1,4-lactone + H2O <=> D-galactonate + H+

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction in which it was curated.

The reaction is physiologically favored in the direction shown.

In Pathways: galactose degradation II

Lactonase activity was assayed in cell extracts. Lactonase activity was increased by growth in the presence of either galactose or L-arabinose [Arias86].
