Any enzyme that catalyzes the synthesis of a biological compound. / (dated) Such an enzyme that, more specifically, does not use ATP as a source of energy.

plural of synthase

(biochemistry) An enzyme that catalyzes the synthesis of adenosine triphosphate (ATP) from adenosine diphosphate (ADP) and inorganic phosphate.

plural of vetispiradiene synthase

(biochemistry) An enzyme, involved in riboflavin biosynthesis, that catalyzes the chemical reaction 1-deoxy-L-glycero-tetrulose 4-phosphate + 5-amino-6-(D-ribitylamino)uracil ⇌ 6,7-dimethyl-8-(D-ribityl)lumazine + 2 H₂O + phosphate.

(biochemistry) An enzyme found in plants and bacteria, but not in animals, which catalyses the final step in the biosynthesis of tryptophan.

(biochemistry) A ligase enzyme involved in purine metabolism.

(biochemistry) A lyase enzyme that catalyzes the chemical reaction trans,trans-farnesyl diphosphate ⇌ vetispiradiene + diphosphate.

plural of alkylglycerone phosphate synthase

(biochemistry) An enzyme that catalyzes the chemical reaction 1-acyl-glycerone 3-phosphate + a long-chain alcohol ⇌ an alkyl-glycerone 3-phosphate + a long-chain acid anion.
