CC -!- FUNCTION: Part of the ESX-1 / type VII specialized secretion system
CC (T7SS), which exports several proteins including EsxA and EsxB (By
CC similarity). Specific chaperone for cognate PE/PPE proteins, plays an
CC important role in preventing aggregation of PE/PPE dimers (By
CC similarity). Also plays a role in DNA conjugation, in at least
CC recipient strain (PubMed:18554329). {ECO:0000250|UniProtKB:B2HMS9,
CC ECO:0000269|PubMed:18554329}.
CC -!- SUBUNIT: Interacts specifically with ESX-1-dependent PE/PPE proteins
CC (By similarity). {ECO:0000250|UniProtKB:B2HMS9}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:B2HSU5}.
CC -!- DISRUPTION PHENOTYPE: Loss of DNA conjugation when disrupted in
CC recipient strain, strain does not secrete EsxB (PubMed:18554329).
CC {ECO:0000269|PubMed:18554329}.
CC -!- MISCELLANEOUS: DNA conjugation in M.smegmatis is unidirectional with
CC distinct donor and recipient strains; mc(2)155 is a donor strain while
CC MKD8 is a recipient strain. Mutations in a donor strain that alter DNA
CC transfer do not always alter DNA transfer in a recipient strain.
CC {ECO:0000305|PubMed:18554329}.
CC -!- SIMILARITY: Belongs to the EspG family. {ECO:0000305}.
