Hesperidin 6-O-alpha-L-rhamnosyl-beta-D-glucosidase
Hesperidin 6-''O''-alpha--rhamnosyl-beta--glucosidase () is an enzyme with systematic name hesperetin 7-(6-''O''-alpha--rhamnopyranosyl-beta--glucopyranoside) 6-''O''-alpha-rhamnopyranosyl-beta-glucohydrolase. This enzyme catalyses the following chemical reaction : hesperidin + H2O hesperetin + rutinose Rutinose is the disaccharide also known as 6-''O''-α-L- rhamnosyl-D-glucose (C12H22O10) that is present in some flavonoid glycosides. It is prepared from rutin by hydrolysis Hydrolysis (; ) is any chemical reaction in which a molecule of wat ... The enzyme exhibits high specificity towards 7-''O''-linked flavonoid beta-rutinosides. The enzyme is produced by the fungus ''Acremonium'' sp. DSM24697. The genera ''Acremonium'' and morphologically similar ''Stilbella'' have not yet been fully studied on a molecular basis. Under the morphological basis, the fungus ''Stilbella fimetaria'' SES201 was reidentified as ''Acremonium'' sp. SES201 = DSM24697. References External ...

Enzyme
Enzymes () are proteins that act as biological catalysts 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 are Ribozyme, catalytic RNA molecules, called ribozymes. Enzymes' Chemical specificity, specific ...
