title: Placental type of membrane-bound arylamidase (Shiba isoenzyme) found in human cancerous lung.
abstract: A placental type of membrane-bound arylamidase (Shiba isoenzyme) was found in the tissue of adenocarcinoma of the lung. Cancerous lung membrane-bound arylamidase had the same electrophoretic mobility, isoelectric point (pH 4.2), and susceptibility to SDS inactivation as placental membrane-bound arylamidase. Cancerous lung membrane-bound arylamidase had molecular weight and kinetic properties similar to normal lung membrane-bound arylamidase, but differed from the normal lung membrane-bound arylamidase with respect to electrophoretic mobility, isoelectric point, heat stability and inactivation by SDS.
