The first was discovered in Escherichia coli Dps in 1992 [5] and has given the name to the protein family; during stationary phase, Dps binds the chromosome non-specifically, forming a highly ordered and stable Dps-DNA co-crystal within which chromosomal DNA is condensed and protected from diverse damages.

Superoxide dismutase (SOD, EC 1.15.1.1) is an enzyme that alternately catalyzes the dismutation (or partitioning) of the superoxide (O − 2) anion radical into normal molecular oxygen (O 2) and hydrogen peroxide (H
Most mammalian cells exist in an environment where the oxygen concentration is constant, thus responses are not directly stimulated by oxidants. Rather, cytokines such as tumor necrosis factor, interleukin-1 or bacterial polysaccharides induce SOD synthesis and multigene responses. Recent work shows that superoxide is a strong tumor promoter ...
[5] [7] It encodes a mitochondrial matrix protein that forms a homotetramer and binds one manganese ion per subunit. [5] [6] The manganese site forms a trigonal bipyramidal geometry with four ligands from the protein and a fifth solvent ligand. This solvent ligand is a hydroxide believed to serve as the electron acceptor of the enzyme.
Phase 5, Phase V or Phase Five may refer to: Marvel Cinematic Universe: Phase Five, an in-development group of superhero films and television series; Phase5, a hardware manufacturer for the Amiga computer; Deployment phase 5, a final deployment phase of a U.S. Marine Corps reconnaissance force; Pandemic phase 5, the second highest level of a ...
Phase5 was founded in 1992 as subsidiary company of AS&S (Advanced Systems & Software) by Wolf Dietrich and Gerald Carda, which were the owners of AS&S. Phase5 focused on the development of general Amiga hardware, but mainly CPU boards, SCSI controllers and graphics cards.
Proteins of the erythrocyte membrane separated by SDS-PAGE according to their molecular masses. SDS-PAGE (sodium dodecyl sulfate–polyacrylamide gel electrophoresis) is a discontinuous electrophoretic system developed by Ulrich K. Laemmli which is commonly used as a method to separate proteins with molecular masses between 5 and 250 kDa.
Biotinylation at carboxyl groups occur at pH 4.5–5.5. To prevent crossreactivity of the crosslinker with buffer constituents, buffers should not contain primary amines (e.g., Tris , glycine ) or carboxyls (e.g., acetate , citrate ); MES buffer is an ideal choice.
