Dihydroxyacetone kinase in complex with a non-hydrolyzable ATP analog (AMP-PNP). Coordinates from PDB ID:1UN9. [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.
In spite of its name, nattokinase is not a kinase enzyme (and should not be pronounced as such), but a serine protease of the subtilisin family (99.5% identical with aprE). Rather, it is named for the fact that it is an enzyme produced by nattōkin (Japanese: 納豆 菌)(納豆 菌), the Japanese name for Bacillus subtilis var natto.
The structure of the core of PTEN (solved by X-ray crystallography, see figure to the upper right [5]) reveals that it consists primarily of a phosphatase domain, and a C2 domain: the phosphatase domain contains the active site, which carries out the enzymatic function of the protein, while the C2 domain binds the phospholipid membrane.
Above is a ball-and-stick model of the inorganic phosphate molecule (H PO 4 2−).Colour coding: P (orange); O (red); H (white). The chemical activity of a protein kinase involves removing a phosphate group from ATP and covalently attaching it to one of three amino acids that have a free hydroxyl group.
“First you say ‘comma’ like the comma in a sentence,” Amara said. “Then you say ‘la’ like la-la-la-la-la,” added Leela. “OK, let’s practice,” Washington said. Recommended Stories

Phosphorylation of the enzyme GSK-3 by AKT (Protein kinase B) as part of the insulin signaling pathway. [31] Phosphorylation of src (pronounced "sarc") tyrosine kinase by C-terminal Src kinase (Csk) induces a conformational change in the enzyme, resulting in a fold in the structure, which masks its kinase domain, and is thus shut "off".
