Alternative pathways utilize or circumvent putrescine for biosynthesis of putrescine-containing rhizoferrin [PDF]
Journal of Biological Chemistry, 2021 The siderophore rhizoferrin (N1,N4-dicitrylputrescine) is produced in fungi and bacteria to scavenge iron. Putrescine-producing bacterium Ralstonia pickettii synthesizes rhizoferrin and encodes a single nonribosomal peptide synthetase-independent siderophore (NIS) synthetase.
