FunFam 2: Alkyl transferase

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Ditrans,polycis-polyprenyl diphosphate synthase ((2E,6E)-farnesyl diphosphate specific). [EC: 2.5.1.87]
(2E,6E)-farnesyl diphosphate + n isopentenyl diphosphate = n diphosphate + ditrans,polycis-polyprenyl diphosphate (n = 10-55).
  • The enzyme is involved in biosynthesis of dolichol (a long-chain polyprenol) with a saturated alpha-isoprene unit, which serves as a glycosyl carrier in protein glycosylation.
  • The yeast Saccharomyces cerevisiae has two different enzymes that catalyze this reaction.
  • Rer2p synthesizes a well-defined family of polyprenols of 13-18 isoprene residues with dominating C(80) (16 isoprene residues) extending to C(120), while Srt1p synthesizes mainly polyprenol with 22 isoprene subunits.
  • Largest Srt1p products reach C(290).
  • The enzyme from Arabidopsis thaliana catalyzes the formation of polyprenyl diphosphates with predominant carbon number C(120).
