Nice Price for Deoxyribonuclease I



Product name: Deoxyribonuclease I
CAS: 9003-98-9
Description of Deoxyribonuclease I:
Deoxyribonuclease I (DNase I) is a single, glycosylated polypeptide that degrades unwanted single- and double-stranded DNA. The enzyme works by cleaving DNA into 5' phosphodinucleotide and small oligonucleotide fragments. DNase I is commonly added to cell lysis reagents to remove the viscosity caused by the DNA content in bacterial cell lysates or to remove the DNA templates from RNAs produced by in vitro transcription. Two grades of DNAse are offered, one sufficient for protein work and one that is useful for any application requiring the digestion of DNA in which it is crucial to avoid damage to RNA.

Function of Cytochrome C



Product name: Cytochrome C
CAS:9007-43-6
Description of Cytochrome C:
Function:
Cytochrome C is a component of the electron transport chain in mitochondria. The heme group of cytochrome c accepts electrons from the b-c1 complex and transfers electrons to the cytochrome oxidase complex. Cytochrome C is also involved in initiation of apoptosis. Upon release of cytochrome c to the cytoplasm, the protein binds apoptotic protease activating factor.
Cytochrome C can catalyze several reactions such as hydroxylation and aromatic oxidation, and shows peroxidase activity by oxidation of various electron donors such as 2,2-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS), 2-keto-4-thiomethyl butyric acid and 4-aminoantipyrine.

Introduction of Chymotrypsin



Product name: Chymotrypsin
Source:Bovine Pancreas
Description of Chymotrypsin: Chymotrypsin is a digestive enzyme that can perform proteolysis.Chymotrypsin preferentially cleaves peptide amide bonds where the carboxyl side of the amide bond (the P1 position) is a tyrosine, tryptophan, or phenylalanine. These amino acids contain an aromatic ring in their sidechain that fits into a 'hydrophobic pocket' (the S1 position) of the enzyme. The hydrophobic and shape complementarity between the peptide substrate P1 sidechain and the enzyme S1 binding cavity accounts for the substrate specificity of this enzyme.Chymotrypsin also hydrolyzes other amide bonds in peptides at slower rates, particularly those containing leucine at the P1 position.

Introduction of Ribonuclease A


Product name: Ribonuclease A
Description:
Ribonuclease A is the enzyme that digests RNA in our food. Because is it small, stable, and easily purified, ribonuclease has been an important enzyme in biochemical research. It was used by Christian Anfinsen to prove that the sequence of amino acids determines the structure of a folded protein and it was used by Stanford Moore and William Stein to show that a specific arrangement of amino acids is used in the catalytic center of enzymes.
