^aSaturation curves are shown in the Supporting Information (Figure S3). values were computed assuming one active site per subunit and individual subunit masses (Table S1).

^bNo correction was applied to account for the lower purity of YfdE ().

^cDetermined at 50 mM oxalate. This concentration is subsaturating for YfdE forms; the and values given are likely to be lower than the true values.

^dDetermined at 0.75 mM acetyl-CoA.
