Molecular cloning and transcriptional analysis of the Aspergillus terreus gla1 gene encoding a glucoamylase.

ABSTRACT

The Aspergillus terreus gla1 gene, coding for a glucoamylase, has been cloned by heterologous hybridization. The gene is interrupted by four introns and encodes a protein with an N-terminal catalytic domain and a C-terminal starch-binding domain. The expression of the gene is induced by starch and maltose and repressed by glucose.
