doi: 10.1016/j.synbio.2026.01.017
Figure Lengend Snippet: Schematic of constructing engineered Y. lipolytica strain for squalene production. I indicate lipid droplet engineering to modulate triacylglycerols synthesis and increase squalene storage capacity. II indicates modulation of the MVA pathway to promote squalene synthesis flux. III indicates enzyme fusion engineering to promote catalytic efficiency between ERG20 and SQS. IV indicates iterative copy numbering of the ScHMG1 gene. V indicates adaptive evolutionary engineering strategies. Red font represents endogenous genes, and blue font represents heterologous genes.
