UniProt functional annotation for P9WJS9

UniProt code: P9WJS9.

Organism: Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv).
Taxonomy: Bacteria; Actinobacteria; Corynebacteriales; Mycobacteriaceae; Mycobacterium; Mycobacterium tuberculosis complex.
 
Function: Part of an export system, which is required for biosynthesis and secretion of siderophores. Essential for virulence. {ECO:0000269|PubMed:23431276}.
 
Subunit: Interacts with MmpL4. Can also interact with MmpL5. {ECO:0000269|PubMed:23431276}.
Subcellular location: Cell inner membrane {ECO:0000269|PubMed:23431276}; Single-pass membrane protein {ECO:0000255}.
Induction: Transcriptionally regulated by MmpR5 (PubMed:24737322). Repressed by iron and IdeR (PubMed:12065475). {ECO:0000269|PubMed:12065475, ECO:0000269|PubMed:24737322}.
Disruption phenotype: Deletion mutant does not exhibit a low iron growth phenotype, but has attenuated virulence compared to the wild- type strain. Deletion of both mmpS4 and mmpS5 drastically decreases synthesis and secretion of siderophores, and greatly reduces virulence in mice. {ECO:0000269|PubMed:23431276}.
Similarity: Belongs to the MmpS family. {ECO:0000305}.
Sequence caution: Sequence=AAC26395.1; Type=Erroneous initiation; Evidence={ECO:0000305};
