CC -!- FUNCTION: May help regulate assembly and function of the type VII
CC secretion system (T7SS) (PubMed:25865481). EsxA disassembles pre-formed
CC EccC-EsxB multimers, possibly by making EccC-EsxA-EsxB trimers instead
CC of EccC-EsxB-EsxB-EccC tetramers (PubMed:25865481).
CC {ECO:0000269|PubMed:25865481}.
CC -!- SUBUNIT: Forms a tight 1:1 complex with EsxB (PubMed:25865481). Forms a
CC complex with EccC and EsxB, probably wholly mediated by EsxB
CC (PubMed:25865481). {ECO:0000269|PubMed:25865481}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P9WNK7}.
CC Note=Probably secreted via the ESX / type VII secretion system (T7SS).
CC {ECO:0000305|PubMed:25865481}.
CC -!- SIMILARITY: Belongs to the WXG100 family. ESAT-6 subfamily.
CC {ECO:0000305}.
