Pantoate kinase

Pantoate kinase (, PoK, TK2141 protein) is an enzyme with systematic name ATP:(R)-pantoate 4-phosphotransferase. This enzyme catalyses the following chemical reaction


 * ATP + (R)-pantoate $$\rightleftharpoons$$ ADP + (R)-4-phosphopantoate

The conversion of (R)-pantoate to (R)-4'-phosphopantothenate is done during biosynthesis of 4'-phosphopantetheine,.
