Polo kinase
Template:Short description Template:Infobox enzyme In enzymology, a polo kinase (Template:EC number) is a kinase enzyme i.e. one that catalyzes the chemical reaction
- ATP + a protein ADP + a phosphoprotein
Thus, the two substrates of these enzymes are ATP and protein, whereas their two products are ADP and phosphoprotein.
These enzymes belong to the family of transferases, specifically those transferring a phosphate group to the sidechain oxygen atom of serine or threonine residues in proteins (protein-serine/threonine kinases).
The systematic name of this [polo[-like] kinase] enzyme class is ATP:protein phosphotransferase (spindle-pole-dependent).
Examples and other names in common use include Cdc5, Cdc5p, Plk, PLK, Plk1, Plo1, POLO kinase, polo serine-threonine kinase, polo-like kinase, polo-like kinase 1, serine/threonine-specific Drosophila kinase polo, and STK21.
These enzymes participate in 3 metabolic pathways: cell cycle, cell cycle - yeast, and progesterone-mediated oocyte maturation.
Structural studies
As of late 2007, 5 structures have been solved for this class of enzymes, with PDB accession codes Template:PDB link, Template:PDB link, Template:PDB link, Template:PDB link, and Template:PDB link.
