X-RAY CRYSTAL STRUCTURE OF 5'-FLUORODEOXYADENOSINE SYNTHASE FROM STREPTOMYCES CATTLEYA COMPLEXED WITH 2'DEOXY-5'DEOXY-FLUOROADENOSINE.
Overview
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.
About this Structure
2C5B is a Single protein structure of sequence from Streptomyces cattleya with and as ligands. Active as Adenosyl-fluoride synthase, with EC number 2.5.1.63 Known structural/functional Site: . Full crystallographic information is available from OCA.
