Evidence for a second arylhydroxamic acid acyltransferase species in the small intestine of the rat.
The small intestine of the Sprague-Dawley rat has been shown to contain two species of arylhydroxamic acid acyltransferases. These enzymes were separable by gel filtration on Sephadex G-100. The smaller species had the mobility of rat liver acyltransferase and was precipitated with antiserum directed against the liver enzyme. The larger species was not precipitated with this antiserum. These species differ in their relative abilities to utilize N-hydroxy-N-2-acetylaminofluorene (N-hydroxy-AAF) and N-hydroxy-N-4-acetylaminobiphenyl (N-hydroxy-AABP) as substrates, and in their inhibition by non immune serum.
