(chem) (alc) A protein that is capable of speeding up specific chemical reactions by lowering the required activation energy, but is unaltered itself in the process; a biological catalyst An organic substance produced in the cells of living organisms; enzymes are produced by BACTERIA or FUNGI and are used in the liquefication and saccharification steps of ALCOHOL production (Greek enzymes, leavened, from en, in + zyme, leaven) F - enzymes S - enzimas

An enzyme is a chemical substance that is found in living creatures which produces changes in other substances without being changed itself. a chemical substance that is produced in a plant or animal, and helps chemical changes to take place in the plant or animal (enzym, from zyme ). Substance that acts as a catalyst in living organisms, regulating the rate at which life's chemical reactions proceed without being altered in the process. Enzymes reduce the activation energy needed to start these reactions; without them, most such reactions would not take place at a useful rate. Because enzymes are not consumed, only tiny amounts of them are needed. Enzymes catalyze all aspects of cell metabolism, including the digestion of food, in which large nutrient molecules (including proteins, carbohydrates, and fats) are broken down into smaller molecules; the conservation and transformation of chemical energy; and the construction of cellular materials and components. Almost all enzymes are proteins; many depend on a nonprotein cofactor, either a loosely associated organic compound (e.g., a vitamin; see coenzyme) or a tightly bound metal ion (e.g., iron, zinc) or organic (often metal-containing) group. The enzyme-cofactor combination provides an active configuration, usually including an active site into which the substance (substrate) involved in the reaction can fit. Many enzymes are specific to one substrate. If a competing molecule blocks the active site or changes its shape, the enzyme's activity is inhibited. If the enzyme's configuration is destroyed (see denaturation), its activity is lost. Enzymes are classified by the type of reaction they catalyze: (1) oxidation-reduction, (2) transfer of a chemical group, (3) hydrolysis, (4) removal or addition of a chemical group, (5) isomerization (see isomer; isomerism), and (6) binding together of substrate units (polymerization). Most enzyme names end in -ase. Enzymes are chiral catalysts, producing mostly or only one of the possible stereoisomeric products (see optical activity). The fermentation of wine, leavening of bread, curdling of milk into cheese, and brewing of beer are all enzymatic reactions. The uses of enzymes in medicine include killing disease-causing microorganisms, promoting wound healing, and diagnosing certain diseases
A protein produced by living cells that regulates the speed of chemical reactions involved in the metabolism of living organisms, without itself being altered in the process; also called a biological catalyst (Biotech Basics)
an assay that relies on an enzymatic conversion reaction and is used to detect the presence of specific substances (such as enzymes or viruses or antibodies or bacteria)
A special type of protein Enzymes help the body's chemistry work better and more quickly Each enzyme usually has its own chemical job to do such as helping to change starch into glucose (sugar)
Enzymes are biological catalysts capable of speeding up biochemical reactions in the cells of living organisms or in industrial processes They are very specific, which means fewer unwanted by-products Because they can catalyze a specific reaction many thousands of times over, only very small quantities are needed Enzymes can replace harsh chemicals and save energy and resources Being by nature proteins means that they are fully biodegradable after use
A large class of complex protein molecules that encourage biochemical reactions (digestion) Amylase and protease enzymes are the type most frequently encountered in the textile cleaning industry, primarily as spotters or deodorants Enzymes are most effective in neutral environments, at moderate temperatures, and after a dwell time in excess of twenty (20) minutes
Protein entities thought to be manufactured within the cells that are capable of creating simple to complex chemical reactions without themselves being changed Some enzymes can process more than two million chemical reactions in less than a minute Enzymes can also transform some molecules into others creating new molecules When enzyme levels in organisms fall below certain levels, life ceases Most metabolic enzymes in organisms including plants are killed at temperatures exceeding 118 degrees Fahrenheit
Complex proteins, produced by body cells, which are crucial catalysts for biochemical reactions and for building or synthesizing most compounds in the body Each has a specific function; for example, the digestive enzyme lactase breaks down lactose (a sugar in milk) into glucose, which the body can absorb
Orgainic compounds which facilitate various reactions The enzymes which are most important in brewing are amylase enzymes (which convert starches into sugars), and proteolytic enzymes (which break complex proteins down into simpler proteins and amino acids)
Proteins that act as catalysts for most reactions In brewing enzymes are involved in starch conversion, proteolysis, and yeast metabolism Enzymes can be affected by conditions such as temperature, time, and pH
are proteins secreted by cells which act as catalysts to induce chemical changes in other substances, themselves remaining apparently unchanged by the reaction
proteins which speed up chemical reactions inside the body Enzymes play an essential role in unzipping the DNA double helix, and so enabling it to reproduce and to send out the instructions for building proteins
Enzymes are proteins that serve as biological catalysts "Biological" washing powders contain enzymes to break down stain materials They are very specific catalysts and one enzyme catalyses only one, or a small range of, reactions
Any of a group of enzymes that catalyze the cleavage of DNA at specific sites to produce discrete fragments, used especially in genetic engineering. Also called restriction endonuclease. Protein (more specifically, an endonuclease) produced by bacteria that cleaves DNA at specific sites along its length. Thousands have been found, from many different bacteria; each recognizes a specific nucleotide sequence. In the living bacterial cell, these enzymes destroy the DNA of certain invading viruses (bacteriophages), thus placing a "restriction" on the number of viral strains that can cause infection; the bacterium's own DNA is protected from cleavage by methyl (CH3) groups, which are added by enzymes at the recognition sites to mask them. In the laboratory, restriction enzymes allow researchers to isolate DNA fragments of interest, such as those that contain genes, and to recombine them with other DNA molecules; for this reason they have become very powerful tools of recombinant DNA biotechnology (see DNA recombination)
