API processing occurs via autophagy during fermentation. Western blot analysis of cell lysates from wild-type diploid (S288C) and atg19Δ and atg1Δ homozygous diploids at days 1, 2, and 4 of fermentation. Blots were probed with anti-API antibody. Arrows point to the precursor form (pAPI) and the mature form (mAPI) of API. API, aminopeptidase I.
