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 | 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; |
PATHWAY | Quinol/quinone metabolism; menaquinone biosynthesis. |
SIMILARITY | Belongs to the PNP/UDP phosphorylase family. Futalosine hydrolase subfamily. |
