Characterization of the Aspartate Transcarbamoylase that is Found in the pyrBC" Complex of Bordetella Pertussis
An aspartate transcarbamoylase (ATCase) gene from Bordetella pertussis was amplified by PCR and ligated into pT-ADV for expression in Escherichia coli. This particular ATCase (pyrB) was an inactive gene found adjacent to an inactive dihydroorotase (DHOase) gene (pyrC'). This experiment was …

Purification and Characterization of Proteolytic Aspartate Transcarbamoylase (ATCase) from Burkholderia cepacia 25416 and Construction of a pyrB1 Knock-out Mutant
… showed that B. cepacia contained a holoenzyme pyrBC complex of 550 kDa comprised of 47 kDa pyrB and 45 kDa pyrC subunits. In the course of purifying the enzyme, trimeric subunits of 140 kDa and 120 kDa were observed as well as a unique proteolysis of the enzyme. The 47 kDa ATCase subunits were …
