In rich media proaminopeptidase I is targeted to the vacuole via the Cvt pathway and during starvation via autophagy. We here identify Atg23 (Ylr431c), a protein of so far unknown function, as a novel component essential for proaminopeptidase I maturation under non-starvation conditions. Maturation of proaminopeptidase I takes place in starved atg23Delta cells. Selective vacuolar targeting of the autophagosomal marker GFP-Aut7 and the accumulation of autophagic bodies during starvation in the presence of phenylmethylsulfonyl fluoride suggest that autophagy occurs in atg23Delta cells but at a reduced rate. In atg23Delta cells mature vacuolar carboxypeptidase Y is present and accumulation of quinacrine suggests no significant defect in vacuolar acidification. Furthermore, growth of atg23Delta cells on nitrocellulose detects no significant secretion of carboxypeptidase Y.
