ENZYME

ENZYME entry: EC 2.5.1.58

Accepted Name
protein farnesyltransferase
Alternative Name(s)
CAAX farnesyltransferase
FTase
Reaction catalysed
L-cysteinyl-[protein] + (2E,6E)-farnesyl diphosphate = S-(2E,6E)-farnesyl-L-cysteinyl-[protein] + diphosphate
Comment(s)
  • This enzyme, along with EC 2.5.1.59 and EC 2.5.1.60, constitutes the protein prenyltransferase family of enzymes.
  • Catalyzes the formation of a thioether linkage between the C-1 of an isoprenyl group and a cysteine residue fourth from the C-terminus of the protein.
  • These protein acceptors have the C-terminal sequence CA(1)A(2)X, where the terminal residue, X, is preferably serine, methionine, alanine or glutamine; leucine makes the protein a substrate for EC 2.5.1.59.
  • The enzymes are relaxed in specificity for A(1), but cannot act if A(2) is aromatic.
  • Substrates of the prenyltransferases include Ras, Rho, Rab, other Ras-related small GTP-binding proteins, gamma-subunits of heterotrimeric G-proteins, nuclear lamins, centromeric proteins and many proteins involved in visual signal transduction.
