Muraymycin D2
Muraymycin D2 is a peptidyl nucleoside natural product derived from Streptomyces spp., possessing competitive translocase I (MraY) inhibitory activity and antibacterial activity. Muraymycin D2 competitively binds to the nucleotide-binding pocket of the MraY substrate via its nucleoside moiety, and upon binding, induces a conformational change in MraY, blocking lipid I synthesis and inhibiting peptidoglycan biosynthesis. Muraymycin D2 exhibits a Ki of 7.6 nM against Bacillus subtilis and an IC50 of 0.39 nM against Staphylococcus aureus. Muraymycin D2 shows antibacterial activity against Escherichia coli and is capable of breaking persistence in chlamydial infection. Muraymycin D2 can be used for research on bacterial infection-related studies, such as chlamydial infection.

In Vitro
Muraymycin D2 competitively inhibits Bacillus subtilis MraY with a Ki of 7.6 nM[1].
Muraymycin D2 (MRY D2) induces enlarged abnormal cells in C. trachomatis D/UW-3/CX, with an MIC of 128 µg/mL[2].
Muraymycin D2 (0.05-0.5 µM; 90 min) inhibits the enzymatic activity of purified C. pneumoniae MraY[2].
Muraymycin D2 (128 µg/mL; 18 h) eradicates persistent C. trachomatis D/UW-3/CX cells in PEN G-induced infection; when applied at the mid-stage, it reduces inclusions in active C. trachomatis D/UW-3/CX infection[2].
Muraymycin D2 binds to A. aeolicus MraY, inducing significant conformational changes and specific binding interactions[1].
Muraymycin D2 exhibits non-Michaelis-Menten kinetics and substrate inhibition with Mur29, giving Km = 41 μM and kcat = 4.0 min−1; it also exhibits non-Michaelis-Menten kinetics and substrate inhibition when reacted with Mur28, with Km = 170 μM and kcat = 5.2 min−1[3].
Muraymycin D2 is regioselectively phosphorylated by the Mg·ATP-dependent 3''-phosphotransferase Mur28 to generate D2-PHOS; the phosphorylated muraymycin D2 exhibits significantly reduced inhibitory activity against S. aureus MraY[3].
