We investigated the cause for resistance to TCDD toxicity in TGFα mutant wa-1 mice (wa/wa) as compared to its wild-type C57BL/6J(+/+) counterpart. For this purpose after 1 or 10 days TCDD (115 µg/kg) exposure, liver samples were isolated. Biochemical investigations revealed that wa/wa mice showed de

Abstract
The distribution and kinetic parameters of tyrosinase (EC 1.14.–18.1) from anagen hair follicles of the C57BL/6J mouse and several c‐locus mutants were investigated. The results showed that c‐locus mutations not only influenced the total tyrosinase activity, but the subcellular distribution as well. The kinetic parameters of tyrosinase were not influenced by the pigment mutations, suggesting that the mutations were not influencing the structure of the enzyme.
