Activities of delta-aminolevulinic acid synthetase (ALA-S) and delta-aminolevulinic acid dehydratase (ALA-D) in trout liver and kidney were compared with those in the mouse. 2. ALA-S activity (per unit tissue fresh weight) exceeded ALA-D activity in trout liver and kidney. 3. In trout kidney, ALA-S activity slightly exceeded, and ALA-D activity far exceeded, their activities in trout liver. 4. In trout, heme synthesis differs from that in mammals in that appreciable synthesis occurs in the kidney, and in that ALA-S activity is not rate limiting.
