Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst.
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.
Dimethylallyl pyrophosphate (or alternatively, -diphosphate) (DMAPP) is an intermediate product of both mevalonic acid (MVA) pathway and DOXP/MEP pathway.
Enzymes are macromolecular biological catalysts.
Tryptophan (IUPAC-IUBMB abbreviation: Trp or W; IUPAC abbreviation: L-Trp or D-Trp; sold for medical use as Tryptan) is one of the 22 standard amino acids and an essential amino acid in the human diet.
In enzymology, a tryptophan dimethylallyltransferase is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are dimethylallyl diphosphate and L-tryptophan, whereas its two products are diphosphate and 4-(3-methylbut-2-enyl)-L-tryptophan.
