Enzymatic reaction of: lactonase

Inferred from experiment

D-galactono-1,4-lactone + H2O → D-galactonate + H+

The direction shown, i.e. which substrates are on the left and right sides, is in accordance with the direction in which it was curated.

The reaction is physiologically favored in the direction shown.

In Pathways: D-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].
