Nonribosomal peptides have diverse bioactivities and can possess unusual moieties at their C-terminus, such as polyamines. In this study, the authors identify a class of dodecapeptides glidonins that feature diverse N-terminal modifications and a uniform putrescine moiety at the C-terminus, elucidate their biosynthesis, and introduce the putrescine into the C-terminus of other nonribosomal peptides.
