The enzymology used in the biodesulfurization process offers a sustainable and ecologically friendly alternative to conventional sulfur removal methods from fossil fuels. Specific microbial enzymes enable a series of enzymatic reactions that selectively break down sulfur-containing compounds, such as dibenzothiophene (DBT), while preserving the hydrocarbon structure. DszA, DszB, and DszC are key enzymes in the 4S pathway that catalyze the slow transformation of DBT into non-toxic metabolites such as 2-hydroxybiphenyl (2-HBP). Additional enzyme pathways, such as the Kodama pathway, aid in the complete mineralization of sulfur, demonstrating the versatility of microbial systems in sulfur metabolism. Recent advances in enzymology have allowed for a deeper knowledge of the structure, function, and catalytic processes of desulfurizing enzymes. This has made it possible to use protein engineering and guided evolution to increase the stability and activity of these enzymes. Furthermore, the combination of omics technology and computational modeling has proved extremely helpful in comprehending the control of enzyme pathways and their interactions within microbial systems. Despite these advancements, issues persist, including as low catalytic efficiency in industrial settings, substrate selectivity, and enzyme inhibition. Innovative biotechnological solutions to these limitations are necessary to optimize the biodesulfurization process and expand it for commercial use. This abstract highlights key enzymatic components and recent advancements in the field of biodesulfurization enzymology to highlight the promise of biodesulfurization as a sustainable alternative to greener energy production.
