| Rab geranylgeranyltransferase | <enzyme> Multisubunit enzyme that prenylates GTP-binding proteins terminating in cys-x-cys or cys-cys Registry number: EC 2.5.1.- Synonym: rab gg transferase, rab geranylgeranyl transferase (26 Jun 1999) |
|---|
| rab gene | 1. <molecular biology> One of the three main groups of ras like genes specifying small GTP-binding proteins (the others are ras and rho). Rab proteins are involved in vesicular traffic and seem to control translocation from donor to acceptor membranes. 2. <cell biology> Gene family in plants responsive to abscisic acid: encode proteins of 15-17 kD. (18 Nov 1997) |

| ras protein geranylgeranyltransferase | <enzyme> Mammalian enzyme transfers geranylgeranyl groups to a cysteine residue fourth from the c-terminal group of a p21 ras protein, prefers leucine at the cooh terminus; see also rhoa geranylgeranyltransferase and protein geranylgeranyltransferase Registry number: EC 2.5.1.- Synonym: geranylgeranyltransferase ras protein, ras protein gg transferase, ggtase I, caax geranylgeranyl transferase (26 Jun 1999) |
