CC -!- FUNCTION: Involved in the biosynthesis of fluorometabolites. Catalyzes
CC the formation of a C-F bond by combining S-adenosyl-L-methionine (SAM)
CC and fluoride to generate 5'-fluoro-5'-deoxyadenosine (5'-FDA) and L-
CC methionine. It can also use 2'-deoxyadenosine in place of adenosine as
CC substrate. {ECO:0000269|PubMed:12860396, ECO:0000269|PubMed:14765200,
