Kinetics of Retinoid Synthesis for atROL, 11cROL, and Palm-CoA Substrates^a

	Vmax (nmol min−1 mg−1)				KM (μM)
substrate	11cREs	11cROL	atREs	atROL	11cREs	11cROL	atREs	atROL
atROL	0.82	0.19	0.28	–	13.5	10.1	10.9	–
11cROL	0.17	–	0.04	0.14	12.1	–	13.0	35.0
palm-CoA	0.99	0.23	0.27	–	34.4	28.5	13.2	–

^aDeterminations for atROL and 11cROL were carried out at 100 μM palm-CoA. Determinations for palm-CoA were carried out at 50 μM atROL.
