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