A method is described for partial purification of structurally bound adenilate desaminase from rat liver tissue mitochondria; the enzyme was stimulated by parenteral administration of serotonine. The enzymatic preparations obtained desaminated AMP, 2',3'-AMP and adenosine, but they did not effect on ATP, 2',3'-cycloAMP or 3',5'-cycloAMP. The maximal rate of desaminating of these substances by AMP-desaminase, stimulated with serotonine, exceeded approximately 1.4-fold the same values, which were obtained for the enzymatic preparations from liver tissue mitochondria of rats, administered with physiological solution. Mitochondrial serotomine-stimulated adenilate desaminase was differentiated from the other soluble adenilate desaminases by some properties; the enzyme was likely to participate also in the regulation of nucleotides balance in the organism.
