Functional analysis of the methanobactin-encoding gene cluster of Methylocystis sp. strain SB2

ABSTRACT Methanobactins (MBs) are ribosomally synthesized, post-translationally modified polypeptides that have high binding affinities for copper. The key step for post-translational modification of the MB polypeptide precursor is the formation of two heterocyclic rings (pyrazin...
