'''CRYSTAL STRUCTURE OF THE APO FORM OF THE 5'-FLUORO-5'-DEOXYADENOSINE SYNTHASE ENZYME FROM STREPTOMYCES CATTLEYA'''<br />


==Overview==
==Crystal structure of the apo form of the 5'-Fluoro-5'-deoxyadenosine synthase enzyme from Streptomyces cattleya==
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.

[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.
