Purification and Characterization of Proteolytic Aspartate Transcarbamoylase (ATCase) from Burkholderia cepacia 25416 and Construction of a pyrB1 Knock-out Mutant
… 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 cleaved to 40 kDa proteins, which still demonstrated high activity …
