ON A MECHANISM OF SUPPRESSOR GENE REGULATION OF TRYPTOPHAN SYNTHETASE ACTIVITY IN NEUROSPORA CRASSA

Abstract
Suppressor gene ac-tion may in certain cases be concerned with the expression of enzyme activity rather than with enzyme formation. In the Neurospora tryptophan synthetase system, the suppressor gene does not appear to provide "information" necessary for the synthesis of a structurally normal enzyme.
