Functional in vivo studies of the Neurospora crassa cys-14 gene upstream region: importance of CYS3-binding sites for regulated expression.

Sulphate transport in Neurospora crassa is achieved by two distinct sulphate permeases, I and II, encoded by the cys-13 and cys-14 genes, respectively. The synthesis of both sulphate permeases is subject to sulphur repression and requires the global positive-acting regulatory protein CYS3, CYS3, a bZIP DNA binding protein, regulates cys-14 expression at the… (More)
