标题:Biosynthesis Of Virginiae Butanolide A,A Butyrolactone Autoregulator From Streptomyces
摘要:Virginiae Butanolide A (Vb A) (3) Is One Of The Virginiamycin-Inducing Factors From Streptomyces Virginiae And Has A Unique 2,3-Disubstituted Butanolide Skeleton Which Is Common To Other Signal Molecules In Streptomyces. The Biosynthesis Of 3 In Streptomyces Antibioticus,A High Producer Of 3,Was Studied By Experiments With Labeled Precursors. C-13 And H-2 NMR Results As Well As Ci-Ms Analyses Of Dibenzoate Samples Indicated That The Probable Biosynthetic Pathway To 3 Involved Coupling Between A Beta-Keto Acid Derivative And A C3 Unit From Glycerol,Such As Dihydroxyacetone Or A Derivative.
