Application


  • Pseudomonas syringae pv. tomato DC3000 CmaL (PSPTO4723), a DUF1330 family member, is needed to produce L-allo-isoleucine, a precursor for the phytotoxin coronatine: This study demonstrates the essential role of L-allo-isoleucine in the synthesis of plant toxins, impacting plant pathology and biocontrol strategies (Worley et al., 2013).

Biochem/physiol Actions

L-allo-Isoleucine may be used in studies on maple syrup urine disease.

Potential substrates for L-delta-(alpha-aminoadipoyl)-L-(cysteinyl)-D-valine (ACV) synthetase were initially identified using both the amino-acid-dependent ATP<-->pyrophosphate exchange reaction catalysed by the enzyme and the incorporation of 14C-radiolabelled cysteine and valine into potential peptide products. S-Carboxymethylcysteine was an effective substitute for alpha-aminoadipate and

The nonprotein amino acid L-allo-isoleucine is formed endogenously in maple syrup urine disease patients from (R)-3-methyl-2-oxo-pentanoic acid. During strict metabolic balance, the plasma L-allo-isoleucine/L-isoleucine ratio correlates inversely with the residual activity of the branched-chain 2-oxoacid dehydrogenase in fibroblasts and thus

Possible functional differences in the catabolism of the four branched-chain L-amino acids in maple syrup urine disease were assessed using cultured human skin fibroblast stains. Transamination and oxidative decarboxylation were comparatively studied in 90-min incubations with 1 mmole/liter of 1-14C-labeled
