Has acyl esterase, lipase and phospholipase A activity. Peroxisomal import is dependent on the peroxisomal targeting signal type 1 (PTS1) receptor PEX5 and on self-interaction. By oleic acid. Transcriptionally up-regulated by YRM1 along with genes involved in multidrug resistance. Expression is also dependent on RSF1 and RSF2 for transcriptional induction during growth on glycerol-based medium. Aberrant morphology characterized by intraperoxisomal vesicles or invaginations. Present with 2350 molecules/cell in log phase SD medium.
