You searched for: Enzymes
Enzymes accelerate, or catalyze, chemical reactions, and they are known to catalyze more than 5,000 biochemical reaction types. Most enzymes are proteins, although a few are catalytic RNA molecules. Choose specific enzymes for cleaving bonds, removing genomic DNA from RNA preparations, for producing fragments of proteins, or for use in ion exchange chromatography. Enzymes are used in the chemical industry and other industrial applications when extremely specific catalysts are required.
Aldehyde dehydrogenase (from Yeast)
Supplier: Merck
Aldehyde dehydrogenase from baker′s yeast catalyses the reduction of pyridine nucleotides by several aldehydes. It catalyses the oxidation of a wide range of substrates, such as acetaldehyde, formaldehyde, propionaldehyde, n-butylaldehyde, isobutylaldehyde, n-valeraldehyde, caproaldehyde, benzaldehyde, glycoaldehyde, D-glyceraldehyde, malonic semialdehyde, and succinic aldehyde. The enzyme has been used to study the production of ethanol and isobutanol.

alpha-Chymotrypsin
Supplier: Merck
Chymotrypsin (Chy) is a serine protease. It corresponds to a molecular weight of 25,7 kDa and is widely used in pharmaceutical industry.It is synthesized in pancreas from chymotrypsinogen and require calcium for this conversion.α-Chymotrypsin from bovine pancreas (bovine pancreatic α-chymotrypsin, CHT) is an enzyme protein.The influence of varying concentrations of organic solvents like ethanol, 1,4-dioxane and acetonitrile on CHT has been reported.

Pronase E (from Streptomyces griseus)
Supplier: Merck
A mixture of at least three proteolytic activities including an extracellular serine protease. In general, serine proteases display a wide range of substrate specificities, which are believed to be mediated by an active site composed of one Asp, one His, and a Ser residue in the molecule. This enzyme prefers to hydrolyze peptide bonds on the carboxyl side of glutamic or aspartic acid.

Chicken lysozyme (Muramidase) (from egg white)
Supplier: Merck
Lysozyme hydrolyzes β(1→4) linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in peptidoglycan and between N-acetyl-D-glucosamine residues in chitodextrin. Gram-positive cells are quite susceptible to this hydrolysis as their cell walls have a high proportion of peptidoglycan. Gram-negative bacteria are less susceptible due to the presence of an outer membrane and a lower proportion of peptidoglycan. However, these cells may be hydrolyzed in the presence of EDTA that chelates metal ions in the outer bacterial membrane.The enzyme is active over a broad pH range (6,0 to 9,0). At pH 6,2, maximal activity is observed over a wider range of ionic strengths (0,02 to 0,100 M) than at pH 9,2 (0,01 to 0,06 M).
