4,4'-diapophytoene synthase (, dehydrosqualene synthase, DAP synthase, C30 carotene synthase, CrtM) is an enzyme with systematic name farnesyl-diphosphate:farnesyl-diphosphate farnesyltransferase (4,4'-diapophytoene forming). This enzyme catalyses the following chemical reaction
: 2 (2E,6E)-farnesyl diphosphate \rightleftharpoons 4,4'-diapophytoene + 2 diphosphate (overall reaction) : (1a) 2 (2E,6E)-farnesyl diphosphate \rightleftharpoons diphosphate + presqualene diphosphate : (1b) presqualene diphosphate \rightleftharpoons 4,4'-diapophytoene + diphosphate
This enzyme requires Mn2+. It is present in Staphylococcus aureus and some other bacteria such as Heliobacillus sp.
