Abstract

Secondary metabolism provides non-essential products for organisms. Besides playing an important  role in ecological relationships, they may have an appealing biotechnological potential. Among the  most studied microorganisms are fungi, which are known to synthesize a plethora of secondary  metabolites. In order to produce these compounds, the activity of biosynthetic gene clusters (BGCs) is  often necessary. The recent advance of DNA sequencing technologies has rendered the use of genomic  data more accessible. Therefore, the use of in silico methodologies allows the inference of natural  compound production. In this study we exemplify the prediction of secondary metabolism BGCs from  the genome of the fungus Penicillium echinulatum, making use of the antiSMASH tool. The most  abundant families of secondary metabolites found for P. echinulatum included synthetic clusters of terpenes, non-ribosomal peptides (NRPs) and clusters similar to NRPs. In addition, the approach  allowed for the identification of 26 BGCs for P. echinulatum, from which clavaric acid,  naphthopyrone, nidulanin A, oxaleimide C, and phyllostictine A are highlighted. In this sense, it is  possible to observe that bioinformatics tools are fundamental in the identification of organisms that  produce compounds of interest, since they optimize processes and reduce costs.
