Comments [?]

Function Catalyzes the hydrolysis of futalosine (FL) to dehypoxanthine futalosine (DHFL) and hypoxanthine, a step in the biosynthesis of menaquinone (MK, vitamin K2).
Catalytic activity RHEA:25904: futalosine + H2O = dehypoxanthine futalosine + hypoxanthine
EC 3.2.2.26
Pathway Quinol/quinone metabolism; menaquinone biosynthesis.
Similarity Belongs to the PNP/UDP phosphorylase family. Futalosine hydrolase subfamily.
