DE   putrebactin synthase.
CA   2 N-(3-carboxypropanoyl)-N-hydroxyputrescine + 2 ATP = putrebactin +
CA   2 AMP + 2 diphosphate + 2 H(+).
CC   -!- Requires Mg(2+).
CC   -!- The enzyme, characterized from the bacteria Shewanella spp. MR-4 and
CC       MR-7, catalyze the last step in the biosynthesis of the siderophore
CC       putrebactin.
CC   -!- The enzyme catalyzes the reaction in two steps - concatenation of two
CC       molecules of N(1)-hydroxy-N(1)-succinylputrescine, followed by
CC       cyclization.
