The present disclosure relates to the use of a
maltose dependent degron to control stability of a
protein of interest fused thereto at the post-translational level. The present disclosure also relates to the use of a
maltose dependent degron in combination with a
maltose-responsive
promoter to control
gene expression at the transcriptional level and to control
protein stability at the post-translational level. The present disclosure also relates to the use of a stabilization construct that couples expression of a
cell-growth-affecting
protein with the production of non-catabolic compounds. The present disclosure further relates to the use of a synthetic maltose-responsive
promoter. The present disclosure further provides compositions and methods for using a maltose dependent degron, a maltose-responsive
promoter, and a stabilization construct, either alone or in various combinations, for the production of non-catabolic compounds in genetically modified host cells.
