Revealing solvent-dependent folding behavior of mycolic acids from Mycobacterium tuberculosis by advanced simulation analysis.

Mycobacterium tuberculosis remains a persistent pathogen, partly due to its lipid rich cell wall, of which mycolic acids (MAs) are a major component. The fluidity and conformational flexibilities of different MAs in the bacterial cell wall significantly influence its properties, function, and observed pathogenicity; thus, a proper conformational description of different MAs in different environments (e.g.

Differential spontaneous folding of mycolic acids from Mycobacterium tuberculosis.

Mycolic acids are structural components of the mycobacterial cell wall that have been implicated in the pathogenicity and drug resistance of certain mycobacterial species. They also offer potential in areas such as rapid serodiagnosis of human and animal tuberculosis. It is increasingly recognized that conformational behavior of mycolic acids is very important in understanding all aspects of their function.
