Effect of D-amino acids on structure and synthesis of peptidoglycan in Escherichia coli.

abstract：:Four genes, dra, tpp, drm, and pup, that specify enzymes involved in the catabolism of nucleosides and deoxynucleosides in Escherichia coli are known to be very closely linked in the order dra-tpp-drm-pup.
