Biological Activity
| ln Vitro | In the cotyledon segments of Xanthium pennsylvanicum Wallr., NSC 16590 (α-aminoisobutyric acid, AIB) has the greatest inhibitory effect on endogenous ethylene synthesis. seeds. At 4 mM, NSC 16590 reduces ethylene production by around 50%, but even at 20 mM, the fragment's O2 absorption is unaffected. Additionally, NSC 16590 prevents the production of ethylene in the stem segments of seedlings of the etiolated pea (Pisum satiuum L. cv. Alaska). The conversion of ACC to ethylene is competitively inhibited by NSC 16590, according to kinetic study of cell-free extracts of etiolated pea shoots [1]. |

| Additional Infomation |
2-aminoisobutyric acid is a rare, non-protein amino acid and end-product of pyrimidine metabolism, excreted in urine and found in some antibiotics of fungal origin. With the exception of a few bacteria, it is non-metabolisable, and therefore used in bioassays. It is functionally related to a propionic acid and an isobutyric acid. It is a tautomer of a 2-aminoisobutanoic acid zwitterion. 2-Aminoisobutyric acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). 2-Aminoisobutyric acid has been reported in Garcinia mangostana, Apis cerana, and Caenorhabditis elegans with data available. |
