WebNov 12, 2013 · Abstract. For nearly 60 years, the ATP activation and the CTP inhibition of Escherichia coli aspartate transcarbamoylase (ATCase) has been the textbook example of allosteric regulation. We present kinetic data and five X-ray structures determined in the absence and presence of a Mg (2+) concentration within the physiological range. WebRegulatory subunit binds to ATP and CTP but does not have any detectable ATCase activity. Reconstituion of regulatory and catalytic subunits (after the removal of mercurial) generates the fully ﬁunctional ATCase. Catalytic and regulatory sites are located on diﬀerent subunits of ATCase.
