title: Intramicrosomal location in intestine of enzymes which synthesize complex lipid.
abstract: Smooth and rough microsomal fractions were prepared from hamster intestinal mucosa and assayed for RNA, diglyceride acyltransferase, cholinephosphotransferase and lysolecithin acyltransferase. The specific activity of cholinephosphotransferase was 4-fold more in the rough than in the smooth microsomal fractions, whereas diglyceride and lysolecithin acyltransferases were respectively 26 and 57% more active in the rough microsomal fraction. The two acyltransferases were similarly located in the microsomes and more closely corresponded to the location of dietary lipid than cholinephosphotransferase.
