Abstract
Non-conventional yeasts are recognized as valuable hosts for producing biofuels, pharmaceuticals, and other high-value chemicals, owing to their diverse physiological traits, ability to utilize various substrates, and greater tolerance to environmental stresses compared to conventional model yeast Saccharomyces cerevisiae. To fully optimizing metabolic flux toward desired products, effective genetic engineering tools enabling precise modulation of gene expression and coordinated control of metabolic pathways are essential. In this context, we discussed classical transcriptional regulation tools like promoters, and transcription factors, alongside innovations in synthetic biology that allow metabolic engineering in non-conventional yeasts to produce higher biofuels and other useful products, promoting the development of sustainable resources, and assisting the development of innovative bio-products. It also discussed innovative programmable technologies, such as CRISPR/Cas-mediated transcriptional activation and repression, as well as dynamic regulatory systems that can fine-tune metabolic routes and balance cellular resources. Strategies for promoter engineering, transcription factor manipulation for transcriptional regulation, and metabolic rewiring were highlight as methods to boost pathway efficiency and yields. This review concluded with current challenges and future directions, focusing on integrating synthetic biology and systems biology to create robust, controllable transcriptional frameworks for next-generation yeast cell factories.
