Bornyl Diphosphate Synthase
In enzymology, bornyl diphosphate synthase (BPPS) () is an enzyme that catalysis, catalyzes the chemical reaction :geranyl diphosphate \rightleftharpoons (+)-bornyl diphosphate Bornyl diphosphate synthase is involved in the biosynthesis of the cyclic monoterpenoid bornyl diphosphate. As seen from the reaction above, BPPS takes geranyl diphosphate as its only substrate and isomerizes into the product, (+)- bornyl diphosphate. This reaction comes from a general class of enzymes called terpene synthases that cyclize a universal precursor, geranyl diphosphate, to form varying monocyclic and bicyclic monoterpenes. The biochemical transformation of geranyl diphosphate to cyclic products occurs in a variety of aromatic plants, including both Flowering plant, angiosperms and gymnosperms, and is used for various purposes described in sections below. Terpene synthases like BPPS are the primary enzymes in the formation of low-molecular-weight terpene metabolites. The organization of terpene s ...

Enzymology
An enzyme () is a protein that acts as a biological catalyst by accelerating chemical reactions. The molecules upon which enzymes may act are called substrate (chemistry), substrates, and the enzyme converts the substrates into different molecules known as product (chemistry), products. Almost all metabolism, metabolic processes in the cell (biology), cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme, pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts include Ribozyme, catalytic RNA molecules, also called ribozymes. They are sometimes descr ...
