Análise estrutural e uso de lacase de camarão para a degradação de antraceno

Through the large population growth and technological development, the use of natural resources has become increasingly present and constant, also causing concerns, measures and solutions related to the environment. In this context, the oil spill has affected aquatic ecosystems. Furthermore, petroleum comprises a series of polycyclic aromatic hydrocarbons, which are not very volatile and are deposited at the bottom of aquatic environments. Therefore, the use of laccase enzymes can be used to combat petroleum hydrocarbons. The structure of the L. vannamei laccase showed conserved domains characteristic of this enzyme, such as those that are important for copper centers, since they are responsible for carrying out the oxidation of aromatic compounds. In addition, the sequence of this enzyme showed a higher percentage of identity when compared to the laccases of other organisms, this fact can be characterized due to the number of identical positions existing between their amino acid sequences. The present work addressed the use of bioinformatics tools to understand the structure of the laccase and, consequently, test the activity of the enzyme in the degradation of the anthracene hydrocarbon.
