Get on the fluor! The fluorinase enzyme from Streptomyces cattleya was identified in 2002 as the only fluorination enzyme known in biochemistry. Three additional fluorinases expressed through bacterial genomemining are now reported. These new fluorinases extend the range of genes available for developing fluorination biotechnology.

shared enzyme catalyzes an aldol-type condensation with glycine and uridine-5'-aldehyde to furnish GlyU. Using LipK involved in A-90289biosynthesis as a model, we now functionally assign and characterize the enzyme responsible for the C-C bond-forming event during GlyU biosynthesis as an l-threonine:uridine-5'-aldehyde transaldolase. Biochemical analysis revealed this transformation is dependent upon p
