a

For detailed reaction conditions see methods section.

b

Specific activities were determined for each reaction, with saturating concentrations of all substrates, in triplicate. Errors reported are the standard deviations from those determinations.

c

Compared to the specific activity in the presence of acetyl-CoA.
