Backbone assignments of the biotin carboxyl carrier protein domain of Propionyl CoA carboxylase of Leishmania major and its interaction with its cognate Biotin protein ligase.

Propionyl CoA carboxylase (PCC) is a multimeric enzyme composed of two types of subunits, α and β arranged in αβ stoichiometry. The α-subunit consists of an N-terminal carboxylase domain, a carboxyl transferase domains, and a C-terminal biotin carboxyl carrier protein domain (BCCP). The β-subunit is made up of an N- and a C- carboxyl transferase domain.
