Protein attributes

Sequence length	311 AA.
Sequence status	Complete.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Catalyzes the transfer of a geranyl-geranyl moiety from geranyl-geranyl pyrophosphate to proteins having the C-terminal-XCC or -XCXC, where both cysteines may become modified By similarity.
Catalytic activity	Geranylgeranyl diphosphate + protein-cysteine = S-geranylgeranyl-protein + diphosphate.
Subunit structure	Heterodimer of an alpha and a beta subunit By similarity.
Sequence similarities	Belongs to the protein prenyltransferase subunit alpha family. Contains 5 PFTA repeats.
