Robust assembly of the aldehyde dehydrogenase Ald4p in Saccharomyces cerevisiae.

ABSTRACT: As part of our studies of yeast aldehyde dehydrogenase (Ald4p) assembly, we identified a population of transformants (SWORD strain) that show more robust filament formation of GFP-tagged Ald4p (Ald4p-GFP) than that of a wild type ALD4::GFP strain. Sequencing of the ALD4 gene in the SWORD strain showed that the increased assembly was not due to changes to the ALD4 coding sequence, suggesting that a second mutation site was altering Ald4p assembly. Using short-read whole-genome sequencing, we identified spontaneous mutations in FLO9. Introduction of the SWORD allele of FLO9 into a wild-type ALD4::GFP yeast strain revealed that the changes to FLO9 were a contributor to the increased length of Ald4p-GFP filaments we observe in the SWORD strain and that this effect was not due to an increase in
