== Function ==
[https://www.uniprot.org/uniprot/FLA_STRCT FLA_STRCT] Involved in the biosynthesis of fluorometabolites. Catalyzes the formation of a C-F bond by combining S-adenosyl-L-methionine (SAM) and fluoride to generate 5'-fluoro-5'-deoxyadenosine (5'-FDA) and L-methionine. It can also use 2'-deoxyadenosine in place of adenosine as substrate.<ref>PMID:12860396</ref> <ref>PMID:14765200</ref> <ref>PMID:16370017</ref> <ref>PMID:16604208</ref> <ref>PMID:16720268</ref> <ref>PMID:17985882</ref>

== Publication Abstract from PubMed ==
The fluorinase enzyme from Streptomyces cattleya displays an unusual ability in biocatalysis in that it forms a C-F bond. We now report that the enzyme will accept 2'-deoxyadenosine in place of adenosine substrates, and structural evidence reveals a reorganisation in hydrogen bonding to accommodate this substrate series. It emerges from this study that the enzyme does not require a planar ribose conformation of the substrate to catalyse C-F bond formation.

Substrate specificity in enzymatic fluorination. The fluorinase from Streptomyces cattleya accepts 2'-deoxyadenosine substrates.,Cobb SL, Deng H, McEwan AR, Naismith JH, O'Hagan D, Robinson DA Org Biomol Chem. 2006 Apr 21;4(8):1458-60. Epub 2006 Mar 8. PMID:16604208<ref>PMID:16604208</ref>
