This invention discloses a
sugar transporter gene. RkMAL1 Its
nucleotide sequence is shown in SEQ ID NO:1, and the
amino acid sequence encoded by this
gene is shown in SEQ ID NO:2. This invention utilizes *
Rhodotorula rubrum* (…). Rhodosporidium kratochvilovae Glycotransporter
gene isolated from ) RkMAL1
uridine diphosphate glucose pyrophosphorylase RkUGPP After ligating the two components to a vector, they were transferred into *
Rhodotorula rubrum* to achieve
gene transfer. RkMAL1、
Gene RkMAL1+RkUGPP Overexpression of the gene significantly improves the synthesis efficiency of
extracellular polysaccharides in recombinant strains. This invention provides a new method for producing
extracellular polysaccharides, which is simple, easy to operate, and offers good application prospects for the large-scale production of
extracellular polysaccharides.
