General annotation (Comments)

Function

Catalyzes the transfer of a farnesyl moiety from farnesyl pyrophosphate to a cysteine at the fourth position from the C-terminus of several proteins. The beta subunit is responsible for peptide-binding.

Catalytic activity

Farnesyl diphosphate + protein-cysteine = S-farnesyl protein + diphosphate.

Cofactor

Binds 1 zinc ion per subunit.

Subunit structure

Heterodimer of an alpha and a beta subunit. Ref.6

Sequence similarities

Belongs to the protein prenyltransferase subunit beta family.

Contains 5 PFTB repeats.

Binary interactions
