| Abstract |
Strain MS14, exhibiting antifungal activity, was classified to belong to Burkholderia contaminans. When compared with the wild type strain, antifungal activities of mutants MS14MT13 and MS14MT18 against Geotrichum candidum were eliminated, and the activity of mutant MS14MT15 was reduced by approximately 80%. Sequence analysis of a 22.7-kb DNA segment revealed the presence of six open-reading frames (ORFs), including the genes disrupted in the mutants. The wild type level of antifungal activity was observed for mutant MS14MT15 (ambR2::Tn5) complemented in trans with the intact ambR2 gene, which encodes a LuxR type regulator. AmbR2 positively regulates the transcription of the other five ORFs identified, which including two nonribosomal peptide synthetase genes required for biosynthesis of antifungal compound. The compound consists of amino acid residues having a molecular weight of 1200.6 Da. These results show that strain MS14 possesses a novel set of genes dedicated to the biosynthesis of an antifungal oligopeptide. |
