Metabolite Identification
Common Name5-Acetamidovalerate
Description5-Acetamidovalerate is involved in the lysine degradation III pathway. It can be generated from the enzymatic reduction of 5-aminopentanoate or enzymatic oxidation of 2-keto-6-acetamidocaproate. Experiment using DL-{4,5-3H}lysine showed 5-acetamidovalerate as the major product. If radiolabeled N6-acetyl-L-lysine was used with added α-ketoglutarate, and pyridoxal phosphate, radiolabeled 2-keto-6-acetamidocaproate was produced. α-Ketoglutarate was preferred over pyruvate, and there was little or no dependence on pyridoxal phosphate. If thiamine pyrophosphate and NAD were added to a similar reaction, virtually all of the label was in 5-acetamidovalerate. If labeled 5-acetamidovalerate was used, labeled 5-aminovalerate (5-aminopentanoate) was identified. In addition, whole cell cultures of R. leguminicola incubated with labeled 5-acetamidovalerate accumulated radiolabeled glutarate. Whole cell cultures incubated with radiolabeled glutarate produced a mixture of tricarboxylic acid cycle acids and other carboxylic acids.
