Summary: Increasing environmental concerns and demand for industrial fuels require the development of alternate and sustainable energy sources. Biodiesel, a renewable and environmentally friendly fuel, is produced by trans-esterifying various feedstocks. Lipases, robust enzymes, can catalyze a range of reactions involved in biodiesel synthesis. Protein engineering techniques can improve the catalytic characteristics of lipases, such as stability, activity, and substrate specificity, enhancing their industrial applicability. This review provides an overview of recent advancements in lipase engineering for biodiesel synthesis.
