Web21 jun. 2016 · Methanobactin reversed acute stages of Wilson’s disease. In order to check if methanobactin is also suitable for binding copper from the body, the researchers used … Methanobactin (mb) is a class of copper-binding and reducing chromophoric peptides initially identified in the methanotroph Methylococcus capsulatus Bath - and later in Methylosinus trichosporium OB3b - during the isolation of the membrane-associated or particulate methane monooxygenase (pMMO). It is thought to be secreted to the extracellular media to recruit copper, a critical component of methane monooxygenase, the first enzyme in the series that catalyzes th…

WebA key player in methanotroph copper homeostasis is methanobactin (Mbn), a ribosomally produced, post-translationally modified natural product with a high affinity for copper. The Mbn precursor peptide is encoded within an operon that contains a range of putative transporters, regulators, and biosynthetic proteins, but the involvement of these genes in … Web1 jan. 2024 · In this chapter, we describe the methods that were used to determine that MbnB and MbnC are the core biosynthetic enzymes in methanobactin biosynthesis. The two proteins form a heterodimeric complex (MbnBC) which, through a dioxygen-dependent four-electron oxidation of the precursor peptide (MbnA), modifies a cysteine residue in …
