WebAspartate transcarbamylase (ATCase) performs an early step in the production of pyrimidine rings, which are used to build nucleotides in DNA and RNA. Early studies found that Escherichia coli ATCase is regulated … WebThe ATCase enzyme is designed to increase the activity within a narrow range of substrate concentrations in the ACTase enzyme complex, CTP binds to the regulatory subunit only In ATCase, there are multiple catalytic subunits. How they associate toghether? They are not associated togueter but associate with Regulatory subunits is string theory realThe allosteric site in the allosteric domain of the R chains of the ATCase complex binds to the nucleotides ATP, CTP and/or UTP. There is one site with high affinity for ATP and CTP and one with 10- to 20-fold lower affinity for these nucleotides in each regulatory dimer. ATP binds predominantly to the high-affinity sites and subsequently activates the enzyme, while UTP and CTP binding leads to inhibition of activity. UTP can bind to the allosteric site, but inhibition of AT… i found light against all odds
