squalene synthase
Cat No.
EXWM-2758
Description
This microsomal enzyme catalyses the first committed step in the biosynthesis of sterols. The enzyme from yeast requires either Mg2+ or Mn2+ for activity. 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.
Form
Liquid or lyophilized powder
Enzyme Commission Number
CAS No.
9077-14-9
Storage
Store it at +4 ºC for short term. For long term storage, store it at -20 ºC～-80 ºC.
Synonyms
farnesyltransferase; presqualene-diphosphate synthase; presqualene synthase; squalene synthetase; farnesyl-diphosphate farnesyltransferase; SQS
Reaction
2 (2E,6E)-farnesyl diphosphate + NAD(P)H + H+ = squalene + 2 diphosphate + NAD(P)+ (overall reaction); (1a) 2 (2E,6E)-farnesyl diphosphate = diphosphate + presqualene diphosphate; (1b) presqualene diphosphate + NAD(P)H + H+ = squalene + diphosphate + NAD(P)+
