Intramicrosomal location in intestine of enzymes which synthesize complex lipid.
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.
