CC   -!- FUNCTION: Catalyzes the hydrolysis of futalosine (FL) to dehypoxanthine
CC       futalosine (DHFL) and hypoxanthine, a step in the biosynthesis of
CC       menaquinone (MK, vitamin K2).
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=futalosine + H2O = dehypoxanthine futalosine + hypoxanthine;
CC         Xref=Rhea:RHEA:25904, ChEBI:CHEBI:15377, ChEBI:CHEBI:17368,
CC         ChEBI:CHEBI:58863, ChEBI:CHEBI:58864; EC=3.2.2.26;
CC   -!- PATHWAY: Quinol/quinone metabolism; menaquinone biosynthesis.
CC   -!- SIMILARITY: Belongs to the PNP/UDP phosphorylase family. Futalosine
CC       hydrolase subfamily.
