A cDNA and genomic gene encoding calmodulin were isolated from Aspergillus oryzae using a part of the calmodulin gene from A. nidulans as a hybridization probe. The gene was in a 3.4-kb SphI fragment and Southern-blot analysis of genomic DNA suggested the existence of a single copy of the calmodulin gene in A. oryzae. The nucleotide sequence analysis showed that the gene consists of five introns and six exons. Although the nucleotide sequence homology with that of A. nidulans was not so high (68%), the deduced amino acid sequence was 100% and 84% identical with calmodulin of A. nidulans and chicken, respectively. The cDNA encoding A. oryzae calmodulin was expressed under the control of the GAL1 promoter in the calmodulin null mutant (cmd1) of yeast, Saccharomyces cerevisiae, and could function as a calmodulin gene.
