Carboxyltransferase domain, subdomain C and D Urea carboxylase (UC) catalyzes a two-step, ATP- and biotin-dependent carboxylation reaction of urea. It is composed of biotin carboxylase (BC), carboxyltransferase (CT), and biotin carboxyl carrier protein (BCCP) domains. The CT domain of UC consists of four subdomains, named A, B, C and D. This domain covers the C and D subdomains of the CT domain. This domain covers the whole length of kipI (kinase A inhibitor) from Bacillus subtilis. It can also be found in S. cerevisiae urea amidolyase Dur1,2, which is a multifunctional biotin-dependent enzyme with domains for urea carboxylase and allophanate (urea carboxylate) hydrolase activity. |
