The general reaction catalyzed by a phosphatase enzyme. Phosphatases catalyze the hydrolysis of a phosphomonoester, removing a phosphate moiety from the substrate. Water is split in the reaction, with the -OH group attaching to the phosphate ion, and the H+ protonating the hydroxyl group of the other product. The net result of the reaction is ...
The active has been shown to contain two binding sites, one designated a water site where hydroxylic molecules such as 1,2-cyclohexanediol and ethylene glycol may bind, and another designated as the acceptor site where the sugar molecule binds. Though the function of the water site has not been completely elucidated, the enzyme's stability in ...
Biological hydrolysis is the cleavage of biomolecules where a water molecule is consumed to effect the separation of a larger molecule into component parts. When a carbohydrate is broken into its component sugar molecules by hydrolysis (e.g., sucrose being broken down into glucose and fructose), this is recognized as saccharification. [2]
In biochemistry, enzymatic hydrolysis is a process in which enzymes facilitate the cleavage of bonds in molecules with the addition of the elements of water (i.e. hydrolysis). It plays an important role in the digestion of food. [1] It may be used to help provide renewable energy, as with cellulosic ethanol. [2]
Hydrolase enzymes are important for the body because they have degradative properties. In lipids, lipases contribute to the breakdown of fats and lipoproteins and other larger molecules into smaller molecules like fatty acids and glycerol. Fatty acids and other small molecules are used for synthesis and as a source of energy. [1]
In biochemistry, a kinase (/ ˈ k aɪ n eɪ s, ˈ k ɪ n eɪ s,-eɪ z /) [2] is an enzyme that catalyzes the transfer of phosphate groups from high-energy, phosphate-donating molecules to specific substrates. This process is known as phosphorylation, where the high-energy ATP molecule donates a phosphate group to the substrate molecule.
Glycolysis is an essential process of glucose degrading into two molecules of pyruvate, through various steps, with the help of different enzymes. It occurs in ten steps and proves that phosphorylation is a much required and necessary step to attain the end products.
Enolase is a member of the large enolase superfamily.It has a molecular weight of 82,000–100,000 daltons depending on the isoform. [3] [4] In human alpha enolase, the two subunits are antiparallel in orientation so that Glu 20 of one subunit forms an ionic bond with Arg 414 of the other subunit. [3]
