More | the beta subunit is primarily composed of alpha helices that are arranged into different shapes. The beta subunit is an alpha-alpha barrel. The beta subunit of GGTase-I consists of 13 alpha helices, with 12 alpha helices folded into an alpha-alpha barrel. This arrangement forms a funnel-shaped cavity in the center of the barrel, where the active sites of GGTase-I is located. This cavity is hydrophobic and contains a number of conserved aromatic residues.

additional information | FTase and GGTase-I recognize the same CAAX sequence motif in a protein substrate and catalyze the attachment of farnesyl and geranygeranyl groups to the protein, respectively. The X is the key residue that determines the farnesylation or geranylgeranylation of the CAAX-containing protein. When X is serine, methionine or glutamine the protein substrate is preferentially activated by FTase, but when X is leucine or phenylalanine the protein substrate is preferentially activated by GGTase-I | Rattus norvegicus |

physiological function | enzyme GGTase-I has a crucial role in the posttranslational modification of Ras proteins. The enzyme is involved in several diseases, e.g. glaucoma via Rho prenylation, and neurological diseases. GGTase-I catalyzes geranylgeranyl isoprenoid linked to the cysteine residue of the CAAX protein through a thioether linkage, which will enhance the hydrophobicity of the CAAX protein. Meanwhile, the formed CAAX-protein-isoprenoid complex is attached to the endoplasmic reticulum surface | Rattus norvegicus |
