Proteinase K is a stable and highly reactive serine protease. Evidence from crystal and molecular structure studies indicates the enzyme belongs to the subtilisin family with an active-site catalytic triad (Asp39-His69-Ser224). It is stable in a broad range of environments: pH, buffer salts, detergents (SDS), and temperature. In the presence of 0.1-0.5% SDS, proteinase K retains activity and will digest a variety of proteins and nucleases in DNA preparations without compromising the integrity of the isolated DNA. Proteinase K is typically used at a concentration of 50-100 μg/ml. It is active with or without the presence of SDS, urea, EDTA or various metal ions, but the activity of proteinase K can be increased by adding the denaturing agents and the structure of proteinase K can be stabilized by addition of Ca 2+. Proteinase K is inactivated by heating to 95°C for 10 minutes or using an inhibitor such as PMSF, AEBSF or DFP. Product Specifications: Proteinase K, RNase/DNase free MOLECULAR BIOLOGY GRADE Molecular Weight: 28.5 kDa Activity: >= 30 U/mg Unit Definition: One unit is defined as the amount of enzyme that will liberate 1.0 μmol tyrosine (Folin-positive amino acid) from casein per minute at 37°C, pH 7.5. Storage / Handling: Store at -20°C. Reconstitute in 50mM Tris-HCl (pH 8.0), 3mM CaCl2.

Nourseothricin is a broad-spectrum antibiotic derived from Streptomyces noursei. In addition to being effective on prokaryotic cells of gram-positive and gram-negative bacteria, various fungi including Candida albicans, and certain DNA and RNA viruses, it is also effective on eukaryotic cells of higher eukaryotes. Nourseothricin functions via a mechanism similar to that of the aminoglycoside antibiotics. It induces miscoding of mRNA and leads to inhibition of protein synthesis. It has been used as a selection agent for cells containing the gene conferring resistance to it. Cells transformed with the gene encoding nourseothricin acetyltransferase (CaNAT1) were resistant to nourseothricin. Nourseothricin is inactivated by acetylation of the β-amino group of the β-lysin. CAS Number: 96737-11-7 Synonyms: Racemomycin A, Yazumycin A, Streptothricin VI, Antibiotic S 15-1A, BRN 6031385, Streptothricin, STREPTOTHRICINS, Streptothricin D sulfate
