Protein
Aminodeoxyfutalosine deaminase
Organism
Nitratiruptor sp. (strain SB155-2)
Function
Catalyzes the deamination of aminodeoxyfutalosine (AFL) into futalosine (FL), a step in the biosynthesis of menaquinone (MK, vitamin K2). To a lesser extent, can also deaminate 5'-methylthioadenosine.
Similarity
Belongs to the metallo-dependent hydrolases superfamily.
