DESCRIPTION
Also known as PGT1_ARATH, GGB, PGGT1B, PGGTI. 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 (CaaX). Seems to exclusively prenylate CaaX substrates with leucine in the terminal position. The beta subunit is responsible for peptide-binding. May negatively regulate abscisic acid (ABA) signaling in guard cells and auxin-induced lateral root initiation., Negatively regulates ABA signaling in guard cells. in negative regulation of auxin-induced lateral root initiation. Heterodimer of an alpha and a beta subunit.
