Abstract: Conventional plastics derived from petroleum cause serious environmental problems, mainly due to pollution and slow degradation. Sustainable alternatives, such as polyhydroxyalkanoates (PHAs), which are produced by microorganisms such as Priestia megaterium (formerly known as Bacillus megaterium), are seen as promising substitutes for these materials due to their biodegradability and biocompatibility capabilities. Genomics and bioinformatics enter this scenario, playing an essential role in identifying PHA genes and proteins in the genome of the bacterium Priestia megaterium strain E1, isolated from soil samples, for biotechnological application to the bacterium. The genomic sequences of the bacterium in question were annotated by the functional annotation tools Prokka and eggNOG-mapper and those sequences with PHA annotation were subjected to local alignments in databases. Swiss- Prot and Reference Sequence Protein. The correspondences of the notes made in these different tools were observed using the Venn Diagram. Next, 3D modeling of the PhaC synthase proteins was carried out using the Phyre 2 and Swiss Model tools. As a result, 25 PHA sequences were noted, distributed among different proteins such as PhaA, PhaB and PhaI, among others. The 3D modeling obtained results that are similar to studies already carried out, which showed more reliability to the annotation process and corroborated scientific evidence on the species as a producer of
