||P.3961 left column top paragraph: "Metabolic labeling experiments illustrate that the cellular CoA concentration fluctuates depending on
the carbon source and growth state of Escherichia coli (refs 8, 10, 18). The regulation of pantothenate kinase appears to be the most important determinant of the CoA biosynthetic rate
since 15 times more pantothenate is produced than is phosphorylated
(primary source), suggesting that a maximum of 25% of the catalytic capacity of the enzyme is expressed in normally growing cells (ref 18)."
