General annotation (Comments)

Function

Catalyzes the transfer of a geranyl-geranyl moiety from geranyl-geranyl pyrophosphate to a cysteine at the fourth position from the C-terminus of proteins having the C-terminal sequence Cys-aliphatic-aliphatic-X. Acts on the Rac1, Rac2, Rap1A and Rap1B proteins. The beta subunit is responsible for peptide-binding.

Catalytic activity

Geranylgeranyl diphosphate + protein-cysteine = S-geranylgeranyl-protein + diphosphate.

Cofactor

Binds 1 zinc ion per subunit.

Subunit structure

Heterodimer of an alpha and a beta subunit. Ref.2

Sequence similarities

Belongs to the protein prenyltransferase subunit beta family.

Contains 4 PFTB repeats.
