Key Amino Acid Residues of the Agt1 Transporter for Trehalose Transport by .

Trehalose is crucial for the stress resistance of , primarily through its stabilization of proteins and membranes. The Agt1 transporter, a member of the Major Facilitator Superfamily, mediates trehalose uptake, a key process for maintaining cellular integrity under stress. Despite its importance, the molecular mechanisms of Agt1-mediated trehalose transport remain underexplored.
