Functional diversity in the pH signaling pathway: an overview of the pathway regulation in Neurospora crassa.

abstract：:Yeast ornithine transaminase is known to be induced by arginine and ornithine, through the action of regulatory elements common to arginase induction. We show here that it is subject to a second induction circuit, that which is responsible for urea amidolyase and urea permease induction by allophanate and defined by t...
