products description :
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.

ncbi summary :
Protein geranylgeranyltransferase type I (GGTase-I) transfers a geranylgeranyl group to the cysteine residue of candidate proteins containing a C-terminal CAAX motif in which 'A' is an aliphatic amino acid and 'X' is leucine (summarized by Zhang et al., 1994 [PubMed 8106351]). The enzyme is composed of a 48-kD alpha subunit (FNTA; MIM 134635) and a 43-kD beta subunit, encoded by the PGGT1B gene. The FNTA gene encodes the alpha subunit for both GGTase-I and the related enzyme farnesyltransferase.[supplied by OMIM, Mar 2010]
uniprot summary :
PGGT1B: 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. Belongs to the protein prenyltransferase subunit beta family. 2 isoforms of the human protein are produced by alternative splicing. Protein type: EC 2.5.1.59; Transferase. Chromosomal Location of Human Ortholog: 5q22.3. Molecular Function: protein geranylgeranyltransferase activity; isoprenoid binding; zinc ion binding; CAAX-protein geranylgeranyltransferase activity; drug binding; peptide binding. Biological Process: protein geranylgeranylation; negative regulation of nitric-oxide synthase biosynthetic process; response to cytokine stimulus; positive regulation of cell proliferation; positive regulation of cell cycle
