3FVE - PubMed Abstract: 
The meso (or D,L) isomer of diaminopimelic acid (DAP), a precursor of L-lysine, is a key component of the pentapeptide linker in bacterial peptidoglycan. While the peptidoglycan incorporated in the highly complex cell wall of the pathogen Mycobacterium tuberculosis structurally resembles that of Escherichia coli, it is unique in that it can contain penicillin-resistant meso-DAP-->meso-DAP linkages ...
