chromatographic analysis of cellular extracts shows that forskolin increases levels of both [ met ] enkephalin pentapeptide and high molecular weight enkephalin-containing peptides , while reserpine causes an increase in [ met ] enkephalin pentapeptide and a concomitant decrease in high molecular weight enkephalin-containing peptides , suggesting enhanced conversion of enkephalin precursor ( s ) to the mature polypeptide hormone .
