Metabolite Identification
Common NameMycobactins
DescriptionMycobactins, also known as mycobactin (m), belongs to the class of organic compounds known as depsipeptides. These are natural or synthetic compounds having sequences of amino and hydroxy carboxylic acid residues (usually α-amino and α-hydroxy acids), commonly but not necessarily regularly alternating. Based on a literature review a significant number of articles have been published on Mycobactins. This compound has been identified in human blood as reported by (PMID: 31557052 ). Mycobactins is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Mycobactins is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.

General function:
Not Available
Specific function:
Part of the ABC transporter complex IrtAB involved in the import of iron-bound mycobactin (Fe-MBT) and carboxymycobactin (Fe-cMBT) (PubMed:16385031, PubMed:19948799) (By similarity). Mycobactins are then reduced by the siderophore interaction domain to facilitate iron release in the bacterial cell (By similarity). Transmembrane domains (TMD) form a pore in the membrane and the ATP-binding domain (NBD) is responsible for energy generation (By similarity). Required for replication in human macrophages and in mouse lungs (PubMed:16385031).
