Metabolite Identification
Common NameCarboxymycobactin
DescriptionCarboxymycobactin is a siderophore belonging to the chemical class of metabolites, specifically involved in iron acquisition. This compound is produced by Mycobacterium tuberculosis (Mtb) and plays a crucial role in the bacterium's ability to scavenge iron from the host environment, particularly under iron-limiting conditions. Carboxymycobactin, along with its counterpart mycobactin, facilitates iron uptake through the IrtAB transporter, although the precise molecular mechanisms of substrate recognition and transport remain unclear (PMID:40436358 ). Both siderophores are essential for Mtb's survival and growth in low-iron media, as evidenced by the drastic reduction in their secretion in rv0455c deletion mutants (PMID:35474308 ). Additionally, studies have shown that the uptake of iron-bound carboxymycobactin is dependent on the iron-regulated protein HupB, which is necessary for the transport of ferri-carboxymycobactin (PMID:33609202 ). This highlights the importance of carboxymycobactin in the iron acquisition strategy of Mtb, underscoring its potential as a target for therapeutic interventions against tuberculosis (PMID:36862179 ).
