Protein

Geranylgeranyl transferase type-1 subunit beta

Gene

CDC43

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the transfer of a geranyl-geranyl moiety from geranyl-geranyl pyrophosphate to proteins having the C-terminal sequence Cys-Ile-Ile-Leu or Cys-Val-Leu-Leu. Acts, among other substrates, on Rho1 and Rho2 and CDC42 proteins. Participates in a RAS-like C-terminal modification of proteins involved in nuclear division and bud growth. It is involved in bud positioning and cell polarity.1 Publication

Catalytic activityi

Geranylgeranyl diphosphate + protein-cysteine = S-geranylgeranyl-protein + diphosphate.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
