however , in addition to their different chromatographic properties , the two kinases differed in molecular weight ( liver , 37,000 ; hepatoma , 56,000 ) , in their response to various divalent metal ions , and in their ability to phosphorylate hepatoma poly ( a ) polymerase ( km 7.9 and 30 microgram/microliter for liver and hepatoma enzymes , respectively ) .
