Conclusion: The structure provides insights into the UC carboxyltransfer reaction.Significance: Our study sheds light on the carboxyltransfer catalysis of biotin-dependent carboxylases in general and the function of the Kip A-Kip I complex involved in sporulation regulation.The BC and BCCP domains of biotin-dependent carboxylases are highly homologous, but their CT domains are distinct.Recently, high resolution crystal structures of the PC (18, 19) and PCC (20) holoenzymes have been reported, which greatly advanced the understanding of biotin-dependent carboxylases.Several structural elements important for the UC carboxyltransfer reaction are found in other biotin-dependent carboxylases and might be conserved within this family, and our data could shed light on the mechanism of catalysis of these enzymes.
A structure of the Kip A-Kip I complex is not currently available, and the UC structure provides a framework to understand the function of this complex.
Currently, there is no information on the molecular basis of catalysis by UC.
We report here the crystal structure of the UC and biochemical studies to assess the structural information.
It is composed of biotin carboxylase (BC), carboxyltransferase (CT), and biotin carboxyl carrier protein (BCCP) domains (Fig. Biotin is covalent linked to a conserved lysine residue in the BCCP domain.
The BC domain carboxylates biotin with concomitant ATP cleavage, and the CT domain subsequently transfers the carboxyl group from biotin to urea, generating allophanate (Fig. The reaction mechanism and domain organization share common features with other biotin-dependent carboxylases, including pyruvate carboxylase (PC), propionyl-Co A carboxylase (PCC), acetyl-Co A carboxylase (ACC) and 3-methylcrotonyl-Co A carboxylase.
