title: Activation of particle associated rat liver guanine deaminase by lecithin and interferences of lecithin in protein precipitation.
abstract: Guanine deaminase solubilized from the "light" mitochondrial fraction of rat liver was activated by lecithin. The activation was proportional to the concentration of lecithin taken in the system. A ratio of 1:1 between the two constituents (protein and lecithin) was at least necessary for complete precipitation.
