abstract：:The tissue distribution of the adenylate kinase isozymes in man has been examined using various substrates. The isozymes attributable to the AK1 and AK2 loci were identified, and an additional set of isozymes probably attributable to a third locus was also found. This locus has been provisionally designated AK3. The A...
