Organism
Mycobacterium smegmatis (strain ATCC 700084 / mc(2)155)
Length
95 amino acids
Function
An exported protein. Unlike its M.tuberculosis counterpart has poor pore forming ability in artificial liposomes, does not undergo conformational change at acidic pH (PubMed:23150662). Mutation of 2 residues to those found in M.tuberculosis (25-TA-26 to IH) alters the properties of this protein so that it inserts into liposomes at acidic pH, forming pores, like its M.tuberculosis counterpart (PubMed:26801203).

Organism
Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv)
Length
95 amino acids
Function
May be critical in pro-bacteria versus pro-host interactions; ESX-1 mediates DNA mediated export (maybe via EsxA). The DNA interacts with host (human) cGAS, leading to cGAMP production and activation of the host STING-TBK-1-IRF-3 signaling pathway that leads to IFN-beta which is thought to be pro-bacteria. Mycobacterial dsDNA also interacts with AIM2-NLRP3-ASC to activate an inflammasome, leading to the pro-host IL-1-beta (PubMed:26048138, PubMed:26048136).
