What's a GeneRIF?

The lack of trehalose transporter Agt1 in Saccharomyces cerevisiae reduces cell tolerance to 51 degrees C and increases lipid peroxidation. The damage is reversed when external trehalose is added during 40 degrees C adaptation, confirming that the reason for the agt1Delta sensitivity is the absence of trehalose at the outside of the lipid bilayer. Agt1 is found into vesicles near to plasma membrane in response to stress.

The AGT1 transporter is required for efficient maltotriose fermentation by S. cerevisiae yeasts, highlighting the importance of this permease for breeding and/or selection programs aimed at improving sluggish maltotriose fermentations.
Title: Molecular analysis of maltotriose active transport and fermentation by Saccharomyces cerevisiae reveals a determinant role for the AGT1 permease.
