Abstract:
Highlights? Esm gene cluster resides on a highly unstable giant plasmid ? EsmA1 and A2 work together to promote the formation of phenazine-1,6-dicarboxylic acid ? Polyketide synthase enzymes EsmB1–B5 catalyze the unique methyl transfer ? Atypical polyketide synthase enzymes EsmD1–D3 catalyze the esterification.
