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 MET and 5F1 as [ligands]. Active as [Adenosyl-fluoride synthase], with EC number [2.5.1.63]. Structure known Active Site: AC1. Full crystallographic information is available from [OCA].
