摘要：

Diaminopimelic acid (DAP) uptake was studied in Bacillus megaterium. The K(m) and V(max) were determined for bacteria grown with or without DAP. The uptake of DAP was shown to be constitutive and unaffected by the presence of other amino acids (including cystine). The concentration of DAP and lysine in the amino acid pool was examined and a procedure for pulse-labelling cell walls developed.
