the bifunctional enzyme catalyzes both diaminopelargonic acid aminotransferase and dethiobiotin synthetase reactions in vitro. In the course of the reaction, the diaminopelargonic acid intermediate is directly transferred from the diaminopelargonic acid aminotransferase active site to the dethiobiotin synthetase active site. The overall reaction is rate limited by the diaminopelargonic acid aminotransferase activity

evaluation of biotin overproduction, biotin production by Bacillus subtilis fermentation can be optimized by addition of exogenous lysine or mutational deregulation of lysine in the producing strain
analysis
-
simple, cheap, and sensitive microplate fluorescence assay for 7,8-diaminopelargonic acid aminotransferase activity, allowing linear detection of 7,8-diaminopelargonic acid in the range of 20 nM to 50 microM. The method relies on the direct detection in the enzymatic reaction mixture of the vicinal diamine 7,8-diaminopelargonic acid derivatized with ortho-phthalaldehyde and 2-mercaptoethanol. The assay was validated with the known inhibitor desmethyl-KAPA, i.e. 8-amino-7-oxopelargonic acid, and adapted to microplate for high-throughput screening
analysis
-
analytical method to measure the enantiomeric excess of substrate 8-amino-7-oxononanoic acid, based on the derivatization of its amine function, by orthophtalaldehyde and N-acetyl-L-cysteine, followed by high pressure liquid chromatography separation. Using this methodology and enantiopure samples of 8-amino-7-oxononanoic acid, it appears that racemization of 8-amino-7-oxononanoic acid occurs rapidly with half-lives from 1 to 8 h, not only in 4 M HCl but also in the usual pH range, from 7 to 9
