A new family of insecticidal crystal proteins was discovered by screening sporulated Bacillus
thuringiensis cultures for oral activity against western corn rootworm (WCR) larvae. B. …

Rifampicin induces cytochrome P450 3c, progesterone 1 6a- catalytic efficiency[Vmax/Km]
observed for the 1 6a-and 6/3-and 6/3-hydroxylation, 17/3-estradiol 2-hydroxylation, benzo [a] …

The binding of the amino steroid, 22-amino-23,24-bisnor-5-cholen-3 beta-ol (22-ABC), to
rabbit liver cytochrome P-450 3c was studied using purified P-450 3c and liver microsomes …

… The present study was carried out in conjunction with work with invertebrates (Schwab,
Reeves, and Turner, unpublished data) and was concerned with comparing the bactericidal …

Two highly purified forms of hepatic cytochrome P-450 were isolated from rabbits treated
with the inducers phenobarbital and 2,3,7,8-tetrachlorodibenzo-p-dioxin. Both forms were …

The macrolide antibiotic rifampicin is a potent inducer of cytochrome P-450-mediated drug
metabolism in humans and rabbits. In this report, we demonstrate that in immature rabbits, …

A variety of compounds that can arise from the metabolism of progesterone in vivo stimulate
the 16 alpha-hydroxylation of progesterone as catalyzed by highly purified, reconstituted …

1. Large, independent variations occur among New Zealand White rabbits in the 21-and 6β-hydroxylation
of progesterone as catalysed by liver microsomes. 2. These reactions are …

Methods. The isolation and preparation of microsomes was as described previously (Dieter
& Johnson, 1982). The sub-forms of P-450 3b were purified by ion-exchange …

The metabolism of 17β-estradiol was examined using both rabbit liver microsomes and highly
purified forms of rabbit liver microsomal cytochrome P-450. The predominant microsomal …
