SubunitTranscarboxylase is composed of three subunits: 1.3S, 5S, and 12S. The core of the enzyme is composed of six 12S subunits. On each side of the core there are three pairs of 5S subunits. Each 5S dimer is attached to the core by two 1.3S subunits. Thus the total number of chains is 30 (6 + 12 + 12).Homohexamer. Transcarboxylase is composed of three subunits: 1.3S, 5S, and 12S.

comments
As annotated in Swiss-prot (P02904), this enzyme is a multienzyme, which is composed of three subunits, 1.3S, 5S, and 12S. The 1.3S subunit (PDB;1dcz, 1dd2) serves as a carrier of carboxyl group from the 12S subunit (PDB; 1on3, 1on9) to the 5S one (see [11]).
The 12 subunit transfers a carboxyl group from the terminal of methyl-malonyl-CoA to the 1.3S subunit, whilst the 5S subunit transfers the carboxyl group from the carrier protein to pyruvate, producing oxalacetate (see [11]).
