D-Alanyl-L-leucine (D-Ala-Leu) is a dipeptide that acts as a source donor of L-Leucine (HY-N0486)[1].
The pip gene coding for the proline iminopeptidase (Pip) of Xanthomonas campestris pv. citri is cloned in an Escherichia coli leuB strain using a selective medium containing the dipeptide D-Alanyl-L-leucine (D-Ala-Leu) as the sole source of l-leucine[1].
