TABLE 1.

CoA-ligase activities in a protein fraction of A. evansii cell extracts precipitated at 60% ammonium sulfate^a

Substance with which cells were grown aerobically	CoA ligase activity (nmol min−1 mg of protein−1) with substrate:
	PA	4-OHPA	B
PA	153	18	37
4-OHPA	17	23	7
B	6	4	196
Phe	194	20	34
PA (anaerobic)	139	21	106
Adipate	5	4	NDb
Acetate	4	3	ND

^aThe cell extracts were the supernatant after centrifugation at 100,000 × g. Enzyme activities were determined by a coupled enzyme-spectrophotometric assay. 

^bND, not determined.
