Futalosine hydrolase

Futalosine hydrolase (, futalosine nucleosidase, MqnB) is an enzyme with systematic name futalosine ribohydrolase. This enzyme catalyses the following chemical reaction


 * futalosine + H2O $$\rightleftharpoons$$ dehypoxanthine futalosine + hypoxanthine

This enzyme catalyses the second step of menaquinone biosynthesis.
