The function of enzymes is to speed up chemical reactions. Enzymes do this by reducing the amount of energy needed for a reaction to occur, reports Arizona State University. More » Science Biology Molecular Biology & DNA

Lysozymes are enzymes that break down bacterial cell walls by catalyzing the hydrolysis of 1,4-beta linkages between N-acetylmuramic acid and the acetyl-D-glucosamine residues in the bacterial wall. Lysozymes can help br... More »

Temperature, pH level and concentrations of enzyme and substrate all affect enzyme functionality. Chemical inhibitors can also affect how enzymes function and reduce their effectiveness. More »

Enzyme specificity refers to the tendency for enzymes to catalyze a specific set of chemical reactions. As explained by the Worthington Biochemical Corporation, some enzymes are absolutely specific and only catalyze one ... More »

The enzymes that break down protein include trypsin, chymotrypsin, pepsin, thermolysin, glutamyl endopeptidase, elastase, bromelain and papain. Trypsin, pepsin, elastase, thermolysin, glutamyl, endopeptidase and chymotry... More »

Bacteria is a major source of restriction enzymes. Bacteria cells use restriction enzymes to cut foreign DNA at specific sites, which stops the DNA from infecting the bacteria. More »

DNA polymerase II is a type of DNA polymerase: a category of enzymes that synthesize identical copies of existing DNA, allowing dividing cells to pass this genetic information on to their daughter cells. DNA polymerase I... More »
