Function
Catalyzes the deamination of aminodeoxyfutalosine (AFL) into futalosine (FL), a step in the biosynthesis of menaquinone (MK, vitamin K2). Is very poorly efficient on 1-(6-amino-9H-purin-9-yl)-1-deoxy-N-ethyl-beta-D-ribofuranuronamide (NECA), adenosine, 5'-methylthioadenosine, 5'-deoxyadenosine, 2'-deoxyadenosine, and AMP as substrate.
