Characterisation of the Aspergillus niger dapB gene, which encodes a novel fungal type IV dipeptidyl aminopeptidase


We have cloned the Aspergillus niger dapB gene. Analysis of its nucleotide sequence and the corresponding protein sequence indicates that the gene encodes a type IV dipeptidyl aminopeptidase (DPP IV). Based upon its deduced sequence we predict the presence of a transmembrane domain in the protein. Furthermore, dapB-overexpressing transformants display an… (More)
