Function

function

An ATPase (shown for residues 72-479) (PubMed:26396239).
Part of the ESX-1 / type VII specialized secretion system (T7SS), which exports several proteins including EsxA and EsxB (PubMed:15687187).
Plays a role in DNA conjugation, in both donor and recipient strains (PubMed:15314236).

Miscellaneous

DNA conjugation in M.smegmatis is unidirectional with distinct donor and recipient strains; mc2155 is a donor strain while MKD8 is a recipient strain. Mutations in a donor strain that alter DNA transfer do not always alter DNA transfer in a recipient strain.
