| 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.
