The abilities of purine- and pyrimidine-requiring mutants to produce six orthophosphate repressible extracellular enzymes, alkaline phosphatase, 5'-nucleotidase, acid phosphatase, two nucleases and ribonuclease N1 were examined by culturing these mutants in low and high phosphate media containing nu
## Abstract The regulation of the synthesis of the enzyme urease (urea amido hydrolase E.C. 3.5.1.5.) in __Neurospora crassa__ was investigated. The biosynthesis of urease is repressed by ammonium ions. Under ammonium excess conditions the specific activity of urease decreases from 0.980 to 0.180 ฮผ
