QA-Y — Aspergillus nidulans FGSC A4

Summary

ANIA_01138 (QA-Y) on chromosome 8 of Aspergillus nidulans FGSC A4 encodes a major facilitator superfamily (MFS) sugar transporter with proton:sugar symporter activity. The gene is associated with carbohydrate transport and monocarboxylic acid metabolism, and its product localises to the plasma membrane. Studies of related genes in other species link the family to quinate permease function and MFS sugar transport, though these associations are not established for QA-Y itself. The gene has also been connected through sequence similarity to proteins from related genes in other species.
