The amino acid composition of cell walls from 4 strains of mycobacteria has been determined by quantitative column chromatography. Glutamic acid, alanine and diaminopimelic acid were major components in each of the cell wall preparations. Aspartic acid, serine, threonine, glycine, isoleucine, leucine and valine were present at probably significant levels in cell walls of one or more, but not all of the mycobacteria. chromatographically detectable amounts of arginine, cystine, histidine, lysine, methionine, phenylalanine, proline and tyrosine were absent from all cell wall preparations.
