A novel carbamoyl-phosphate synthetase from Aquifex aeolicus
A Ahuja, C Purcarea, HI Guy, DR Evans - Journal of Biological Chemistry, 2001 - ASBMB
Aquifex aeolicus, an extreme hyperthermophile, has neither a full-length carbamoyl-
phosphate synthetase (CPSase) resembling the enzyme found in all mesophilic organisms
nor a carbamate kinase-like CPSase such as those present in several hyperthermophilic
archaea. However, the genome has open reading frames encoding putative proteins that
are homologous to the major CPSase domains. The glutaminase, CPS. A, and CPS. B
homologs from A. aeolicus were cloned, overexpressed inEscherichia coli, and purified to …
