PtdIns(3,5)P2 plays a key role in growth and development as evidenced by the preimplantation lethality of the PIKfyve knockout mouse model. [13] The fact that the heterozygous PIKfyve mice are ostensibly normal and live to late adulthood with only ~60% of the wild-type PtdIns(3,5)P2 levels suggests that PtdIns(3,5)P2 might normally be in excess ...
Superoxide dismutase (SOD, EC 1.15.1.1) is an enzyme that alternately catalyzes the dismutation (or partitioning) of the superoxide (O ...
P 1,P 4-bis(5'-adenosyl) tetraphosphate + H 2 O 2 ADP Thus, the two substrates of this enzyme are P1,P4-bis(5'-adenosyl) tetraphosphate and H 2 O , whereas its product is ADP . This enzyme belongs to the family of hydrolases , specifically those acting on acid anhydrides in phosphorus-containing anhydrides.
[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.
Bis(triphenylphosphine)platinum chloride is a metal phosphine complex with the formula PtCl 2 [P(C 6 H 5) 3] 2. Cis- and trans isomers are known. The cis isomer is a white crystalline powder, while the trans isomer is yellow. [3] Both isomers are square planar about the central platinum atom. The cis isomer is used primarily as a reagent for ...
The Lotka–Volterra equations, also known as the Lotka–Volterra predator–prey model, are a pair of first-order nonlinear differential equations, frequently used to describe the dynamics of biological systems in which two species interact, one as a predator and the other as prey.
Bis(2-Hydroxyethyl) terephthalate (BHET) is an organic compound; it is the ester of ethylene glycol and terephthalic acid. Together with 2-hydroxyethyl terephthalic ...
Asmat Bis Poles from New Guinea, Indonesia. A Bisj, Mbis or Bis pole is a ritual artifact created and used by the Asmat people of South-western New Guinea, Indonesia. They are also common in New Zealand, Vanuatu (formerly the New Hebrides). [1] When a village has experienced a number of deaths a Bisfeast is held.
