2328827-1	1990	The cytochrome P-450-dependent aromatase pathway utilizes the androgens testosterone (T) and androstenedione, as substrates for estrogen formation.	Androstenedione	93-108	cytochrome P450 family 4 subfamily F member 3	Homo sapiens	4-20	
1001810-7	1976	Both androstenedione and 16alpha-hydroxytestosterone cause type I spectral perturbations associated with binding to cytochrome P-450 when added to placental microsomes; however, the deltaA390-420 is twice as great in response to saturating amounts of androstenedione than in response to 16alpha-hydroxytestosterone.	Androstenedione	5-20	cytochrome P450 family 4 subfamily F member 3	Homo sapiens	116-132	
2848247-5	1988	The expressed protein was similar in size to human placental aromatase system cytochrome P-450, as detected by immunoblot analysis, and catalyzed the aromatization of androstenedione, testosterone, and 16 alpha-hydroxyandrostenedione.	Androstenedione	167-182	cytochrome P450 family 4 subfamily F member 3	Homo sapiens	78-94	
3104339-6	1987	Purified aromatase cytochrome P-450 displays catalytic characteristics similar to the enzyme in intact microsomes in the aromatization of androstenedione, 19-hydroxyandrostenedione and 19-oxoandrostenedione.	Androstenedione	138-153	cytochrome P450 family 4 subfamily F member 3	Homo sapiens	19-35	
1209686-2	1975	A possible explanation was found when it was shown that androst-4-en-3,17-dione and testosterone could displace bound carbon monoxide from human placental microsomal cytochrome P-450.	Androstenedione	56-79	cytochrome P450 family 4 subfamily F member 3	Homo sapiens	166-182
