The<unk> -kDa culture filtrate protein<unk>  and 6kDaA early secreted antigen target (ESAT-6) complex is a<unk> 0 amino-acid sequence protein. ESAT-6/CFP-10 has a hydrophobic nature as well as a high content of α-helical structures. Resonance structure analysis of the complex reveals two similar helix-turn-helix hairpin structures formed by the individual proteins, which lie anti-parallel to each other and forms a four-helix bundle. Its long flexible arm projecting off the four-helix bundle, formed by the seven amino-acid C-terminal of<unk> , is essential for binding and attaching to the surface of host white blood cells; such as macrophages and monocytes. If this C-terminus is cleaved off, the complex shows greatly reduced attachment ability.
