Comments [?]

Catalytic activity RHEA:18633: 2 ATP + H2O + hydrogencarbonate + L-glutamine = 2 ADP + carbamoyl phosphate + 2 H(+) + L-glutamate + phosphate
EC 6.3.5.5
Pathway Amino-acid biosynthesis; L-arginine biosynthesis; carbamoyl phosphate from bicarbonate: step 1/1.
Pyrimidine metabolism; UMP biosynthesis via de novo pathway; (S)-dihydroorotate from bicarbonate: step 1/3.
Subunit Composed of two chains; the small (or glutamine) chain promotes the hydrolysis of glutamine to ammonia, which is used by the large (or ammonia) chain to synthesize carbamoyl phosphate.
Similarity Belongs to the CarB family.

Comments Bacillaceae, Geobacillus and lactobacillaceae seem to posess two members of this family: one specific for arginine biosynthesis (called CARY_ in ID, and CARB in GN) and the other specific for pyrimidine synthesis (called CARB_ in ID, and PYRAB in GN). Sequence of carB is split into two genes in AQUAE, METJA and METKA. Weird insertion in NOSS1, THEMA and ZYMMO (sequences not shown in alignment).
