Characterization of FabG and FabI of the Streptomyces coelicolor dissociated fatty acid synthase

Streptomyces coelicolor produces fatty acids for both primary metabolism and for biosynthesis of the secondary metabolite undecylprodiginine. The first and last reductive steps during the chain elongation cycle of fatty acid biosynthesis are catalyzed by FabG and FabI. The S. coelicolor genome sequence has one fabI gene (SCO1814) and three likely fabG genes (SCO1815, SCO1345, and SCO1846). We report the expression, purification, and characterization of the corresponding gene products. Kinetic analyses revealed that all three FabGs and FabI are capable of utilizing both straight and branched-chain β-ketoacyl-NAC and enoyl-NAC substrates, respectively. Furthermore, only SCO1345 differentiates between ACPs from both biosynthetic pathways. The data presented provide the first experimental evidence that SCO1815, SCO1346, and SCO1814 have the catalytic capability to process intermediates in both fatty acid and undecylprodiginine biosynthesis.

A NOVEL PROCESS FOR THE PREPARATION OF PREGABALIN

The present invention encompasses novel intermediates of pregabalin, namely 3 -cyano-5 -methyl hexanamide (28) and 3-(amino methyl)-5 methyl hexanamide (29), and processes for their preparation. The invention also encompasses a process for converting the novel pregabalin intermediates into pregabalin, Formula (I): The present invention further provides a cost effective method for the synthesis of (S)-pregabalin, which involves the recovery of mandelic acid and tartaric acid used in the resolution process and recycling them, increasing the yields of the final product formed, which substantially reduced the cost of the production.
