This study presents an analysis of the stromal proteome in its oligomeric state extracted from
highly purified chloroplasts of Arabidopsis thaliana. 241 proteins (88% with predicted cTP) …

Carbamyl phosphate (CP) is well-known as an essential intermediate of pyrimidine and
arginine/urea biosynthesis. Chemically, CP can be easily synthesized from dihydrogen …

Aquifex aeolicus is a deep-branching hyperthermophilic chemoautotrophic bacterium
restricted to hydrothermal vents and hot springs. These characteristics make it an excellent …

Aquifex aeolicus, an organism that flourishes at 95° C, is one of the most thermophilic
eubacteria thus far described. The A. aeolicus pyrB gene encoding aspartate …

Metabolism is the consortium of reactions within a cell which directs a variety of processes
including energy synthesis, signalling and the behaviour of a biological system. Metabolic …

Dihydroorotase (DHOase) catalyzes the reversible condensation of carbamoyl aspartate to
form dihydroorotate in de novo pyrimidine biosynthesis. The enzyme from Aquifex aeolicus …

A vast number of prokaryotic and eukaryotic microorganisms can synthesize arginine de
novo from glutamate. The first committed step of this pathway is acetylation of l-glutamate at …

Dihydroorotases (EC 3.5. 2.3) catalyze the reversible cyclization of carbamoyl aspartate to
form dihydroorotate in de novo pyrimidine biosynthesis. The X-ray structures of Aquifex …

Life is based on two aspects: matter and a non-material, electrical component. In a dynamic
system of reciprocal causality, matter and the so-called bioelectricity interact with one …

As glutamate and ammonia play a pivotal role in nitrogen homeostasis, their production is
mediated by various enzymes that are widespread in living organisms. Here, we report on …
