The A. nidulans expression vector which contained trpC marker gene from A. nidulans was constructed to produce glucoamy]ase. The recombinant plasmid was introduced into auxotrophic mutant A. nidulans B17. Southern blot analysis of the genomic DNA from transformant showed that pKHG2 DNA had integrated into the A. nidulans chromosomes. Northern analysis of the total RNA from transform ant showed that mRNA of glucoamylase gene was synthesized in induction condition. Specific activity of glucoamylase was increased in transform ants. G]ucoamylase was shown to be active in non-denaturing acrylamide gel.
