The induction of tryptophan pyrrolase in chick liver by hydrocortisone was studied in copper- and magnesium-deficient chicks. Magnesium deficiency did not influence the induction of the enzyme, whereas copper deficiency significantly decreased it. These results suggest that tryptophan pyrrolase of chick liver, like that in Pseudomonas, is a copper-containing enzyme.
在缺铜和缺镁的雏鸡中研究了氢化可的松对雏鸡肝脏色氨酸吡咯酶的诱导作用。缺镁不影响该酶的诱导，而缺铜则使其显著降低。这些结果表明，雏鸡肝脏的色氨酸吡咯酶与假单胞菌中的一样，是一种含铜酶。
