UbiA prenyltransferase family signature





Description

The following prenyltransferases are evolutionary related [1,2]:

  • Bacterial 4-hydroxybenzoate octaprenyltransferase (gene ubiA).
  • Yeast mitochondrial para-hydroxybenzoate--polyprenyltransferase (gene COQ2).
  • Protoheme IX farnesyltransferase (heme O synthase) from yeast and mammals (gene COX10) and from bacteria (genes cyoE or ctaB).

These proteins probably contain seven transmembrane segments. The best conserved region is located in a loop between the second and third of these segments and we used it as a signature pattern.

Last update:

April 2006 / Pattern revised.
