FunFam 12: Squalene synthase 1

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.

Squalene synthase. [EC: 2.5.1.21]
2 farnesyl diphosphate + NAD(P)H = squalene + 2 diphosphate + NAD(P)(+).
  • This microsomal enzyme catalyzes the first committed step in the biosynthesis of sterols.
  • In the absence of NAD(P)H, presqualene diphosphate (PSPP) is accumulated.
  • When NAD(P)H is present, presqualene diphosphate does not dissociate from the enzyme during the synthesis of squalene from farnesyl diphosphate (FPP).
  • High concentrations of FPP inhibit the production of squalene but not of PSPP.
