In a crude extract of Micrococcus glutaminicus , the reduction of N -acetyl- L -glutamate to N -acetyl-glutamate-5-semialdehyde requires both nicotinamide adenine dinucleotide phosphate-oxidase (NADPH) and adenosine triphosphate (ATP). The reaction happens through the formation of a carboxyl-...
N-acetylglutamate semialdehyde,N-acetylornithine, ornithine, citrulline andN-argininosuccinate are depicted in Figure2.N-acetylglutamyl phosphate was not detectable in any sample examined, which could be due to insufficient ionisation of this compound in positive mode. Arginine...

The primary reaction catalyzed by ArgD is the conversion of N-acetyl ornithine and α-Ketoglutarate into L-glutamate and glutamate-5-semialdehyde that cannot be monitored spectrophotometrically. Hence a secondary reaction that converts one of the products (L-glutamate) of the primary reaction back ...
Cells down-regulated the expression of crucial enzymes of chlorophyll synthesis e.g., glutamate-semialdehyde aminomutase (GJ01010), and Mg-chelatase (GJ00007, GJ01253), and thus use ancient regulatory switches that are well conserved even in land plants [26]. Despite this overall down-...
This review article focuses on the synthesis and reactions of N,N-di-Boc glutamate and aspartate semialdehydes as well as related aldehydes. These building blocks are prepared according to various strategies from glutamic and aspartic acids and find interesting synthetic applications. In the first ...
