A. Tlc analysis of extractable metabolites produced by washed cells of S. viridifaciens vlmH, vlmJ, and vlmK mutants after administration of L-serine and L-valine. B. Tlc analysis of extractable metabolites produced by incubation of 1 with cell-free extracts of vlmJ, vlmK, and vlmH mutants. Val = valanimycin. See Supporting Information for details.
