Microsomes from liver or kidney of untreated rainbow trout hydroxylated lauric acid specifically at the (ω-1) position. Turnover numbers for liver (2.72 min−1) and kidney (14.1 min−1) were decreased seven- and twofold, respectively, following treatment with β-naphthoflavone. Laurate hydroxylation activity from untreated trout hepatic microsomes was sensitive to inhibition by SKF-525A, but was not sensitive to metyrapone and only partially inhibited by α-naphthoflavone. The temperature optimum of laurate (ω-1) hydroxylation in trout liver microsomes was 25–30 °C. TheKmandVmaxfor (ω-1)-hydroxylaurate formation was 50 μmand 1.63 nmol min−1mg−1, respectively, in liver and 20 μmand 3.95 nmol min−1mg−1, respectively, in kidney from untreated trout microsomes. (ω-1) Hydroxylation of laurate, in both liver and kidney microsomes, was sensitive to an antibody raised against a previously purified cytochromeP-450 isozyme (LM2) of trout liver microsomes, which has been shown to be active towards aflatoxin B1. Antibody to the major isozyme of cytochromeP-450 (LM4b, active towards benzo(a)pyrene) induced by β-naphthoflavone did not inhibit (ω-1) hydroxylation of laurate in microsomes from untreated or ω-naphthoflavone-treated trout.
