Abstract: The crystal structures of pseudophomins A and B, with primary structures [beta] -hydroxydecanoyl-L-Leu-D-Glu-D-allo-Thr-D-Ile-D-Leu-D-Ser-L-Leu-D-Ser-L-Ile monohydrate, C₅₅H₉₇N₉O₁₆·H₂O, and [beta] -hydroxydodecanoyl-L-Leu-D-Glu-D-allo-Thr-D-Ile-D-Leu-D-Ser-L-Leu-D-Ser-L-Ile monohydrate, C₅₇H₁₀₁N₉O₁₆·H₂O, new cyclic lipodepsipeptides isolated from Pseudomonas fluorescens strain BRG100, have been solved. The absolute configuration of pseudophomin A has been determined from anomalous dispersion and the stereochemistry of the [beta] -hydroxy acid group is R.

Formula: C₅₅H₉₇N₉O₁₆·H₂O and C₅₇H₁₀₁N₉O₁₆·H₂O
