This family of proteins contains MlaD, which is a component of the Mla pathway, an ABC transport system that functions to maintain the asymmetry of the outer membrane [1]. The family also contains the mce (mammalian cell entry) proteins from Mycobacterium tuberculosis. The archetype (Rv0169), was isolated as being necessary for colonisation of, and survival within, the macrophage [2]. This family contains proteins of unknown function from other bacteria.	Domain

ABC transporters for a large family of proteins responsible for translocation of a variety of compounds across biological membranes. ABC transporters are the largest family of proteins in many completely sequenced bacteria. ABC transporters are composed of two copies of this domain and two copies of a transmembrane domain Pfam:PF00664. These four domains may belong to a single polypeptide as in Swiss:P13569, or belong in different polypeptide chains.	Domain
