Abstract

Bio-manufacturing via microbial cell factory requires large promoter library for fine-tuned metabolic engineering. , one of the methylotrophic yeasts, possesses advantages in broad substrate spectrum, thermal-tolerance, and capacity to achieve high-density fermentation. However, a limited number of available promoters hinders the engineering of for bio-productions. Here, we systematically characterized native promoters in by both GFP fluorescence and fatty alcohol biosynthesis. Ten constitutive promoters (P , P , P , P , P , P , P , P , P and P ) were obtained with the activity range of 13%-130% of the common promoter P (the promoter of glyceraldehyde-3-phosphate dehydrogenase), among which P and P were further verified by biosynthesis of fatty alcohol. Furthermore, the inducible promoters, including ethanol-induced P , rhamnose-induced P and P , and a bidirectional promoter (P -P ) that is strongly induced by sucrose, further expanded the promoter toolbox in . Finally, a series of hybrid promoters were constructed via engineering upstream activation sequence (UAS), which increased the activity of native promoter P by 4.7-10.4 times without obvious leakage expression. Therefore, this study provided a group of constitutive, inducible, and hybrid promoters for metabolic engineering of , and also a feasible strategy for rationally regulating the promoter strength.
