SUT1 — Neurospora crassa

Summary

NCU00450 (SUT1, NcSUT1) on Neurospora crassa chromosome 3 encodes a sucrose transporter belonging to the major facilitator superfamily (MFS_trans_sf). The gene product exhibits sucrose:proton symporter activity and maltose:proton symporter activity, and is associated with the import of sucrose and maltose across the plasma membrane, as well as with fermentation. The protein localises to the fungal-type vacuole membrane, Golgi complex, and plasmalemma. Studies of related genes in other species link the family to general alpha-glucoside permease activity, though these associations are not yet established for N. crassa.
