We have purified and characterized of metalloprotease metalloprotease from Nomuraea atypicola. N. atypicola was cultured in Sabouraud medium supplemented with powdered pupae. The metalloprotease from culture supernatant was purified to electrophoretically homogeneous state. The molecular mass of metalloprotease from N. atypicola was 50 kDa. The enzyme was most active at pH 8.5 and 40oC and stable at pH 5.0-7.0 and up to 40oC. The activity was inhibited by o-phenanthroline and EDTA. The N-terminal amino acid sequence of the enzyme showed a similarity to those of proteases (Metallo peptidase M36 family (Fungalysin)) from Coccidioides posadasii and Aspergillus fumigatus. The enzyme was found to be Fungalysin-like metalloprotease. cDNA encoding metalloprotease from N. atypicola was amplified by PCR using oligonucleotides deduced from the N-terminal endo peptide sequence, 5’- and 3’-RACE. Predicted enzyme structure consists of 637 amino acids with pro- and signal sequences. The mature enzyme had 391 amino acids and its deduced amino acid sequence coincided completely with the N- terminal amino end (20 amino acids) of metalloprotease purified from N. atypicola. We are studying on expression of the metalloprotease gene in Escherichia coli.
