The present study was designed to investigate the hepatic localization of the microsomal bifunctionaltrans-2-enoyl CoA hydratase. Despite the low activity (<10%) of peroxisomal marker enzymes in isolated hepatic microsomes (acyl CoA oxidase (this study), catalase, and urate oxidase (L. Cook, M. N. Nagi, J. Piscatelli, T. Joseph, M. R. Prasad, D. Ghesquier, and D. L. Cinti, 1986,Arch. Biochem. Biophys.245, 24–26), additional evidence in this study suggests that the microsomal enzyme is derived from peroxisomes. For example, the microsomal hydratase activity was associated with the ribosomal fractions but not with the smooth endoplasmic reticulum. In addition, when an extract of the peroxisomal enzyme was incubated with either free ribosomes or membrane-bound ribosomes, marked binding was observed with each of the fractions. Furthermore, the ease of release of the bifunctional enzyme from both free ribosomes and membrane-bound ribosomes by only KCl suggests that the bound enzyme is not a nascent protein. Labeling of liver tissue from DEHP-treated rats with rabbit immune IgG made to the purified microsomal hydratase followed by gold conjugated goat antirabbit IgG suggested a single subcellular site for the bifunctional hydratase—the peroxisomal organelle.
