Induction and Repression of Amidase Enzymes in Aspergillus nidulans

M J Hynes a,1
PMCID: PMC248107  PMID: 5432013

Abstract

Aspergillus nidulans can grow on acetamide as both a carbon and nitrogen source and can also grow on formamide as a nitrogen source. Two distinct enzymes, an acetamidase and a formamidase, are produced. The control of the synthesis of these two enzymes in a wild-type strain was investigated. The formamidase is induced by acetamide and formamide and repressed by ammonia. The acetamidase is induced by formamide and acetamide, repressed by carbon metabolites derived from glucose and acetate, and repressed by ammonia. Repression of the acetamidase by ammonia depends on the carbon source; growth on glucose but not on acetate or acetamide allows repression to occur. The pattern of acetamidase repression is compared with that of histidine catabolic enzymes in various bacteria.
