ABC transporter; part of the gene cluster that mediates the biosynthesis of aspercryptins, linear lipopeptides built from six amino acids including 2 highly unusual and nonproteogenic amino acids, 2-amino-octanoic acid (2aoa) and 2-amino-dodecanol (2adol) (PubMed:23248299, PubMed:27310134, PubMed:26563584). Expression is positively regulated by the aspercryptin cluser-specific transcription factor atnN (PubMed:27310134). Does not alter the yield of aspercryptin significantly (PubMed:26563584). Belongs to the ABC transporter superfamily. ABCC family. Conjugate transporter (TC 3.A.1.208) subfamily.
