General annotation (Comments)

Function

The 12S subunit specifically catalyzes the transfer of the carboxyl group of methylmalonyl CoA to the biotin of the 1.3S subunit forming propanoyl-CoA and carboxylated 1.3S-biotin.

Catalytic activity

(S)-methylmalonyl-CoA + pyruvate = propanoyl-CoA + oxaloacetate.

Subunit structure

Homohexamer. Transcarboxylase 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).

Sequence similarities

Contains 1 carboxyltransferase domain.

Sequence caution

The sequence AAA25676.1 differs from that shown. Reason: Frameshift at several positions.

The sequence CAD59919.1 differs from that shown. Reason: Frameshift at position 519.
