Involved in the synthesis of a cell-wall peptide in bacteria.
The taxonomic range for the selected organisms is: Pseudomonas aeruginosa The expected taxonomic range for this enzyme is: Bacteria, Eukaryota, Archaea
UDP-N-acetylmuramoyl-pentapeptide biosynthesis I (meso-diaminopimelate containing), UDP-N-acetylmuramoyl-pentapeptide biosynthesis II (lysine-containing)
peptides are synthesized from consensus sequences to evaluate their inhibitory potential against the essential MurD enzyme. The C-7-C mers MurDp1 (RPTHSPI) gives a decrease of MurD ATPase activity with a significant IC50 value of 4 mM. The 12 mers MurDp2 (HLPTSSLFDTTG) inhibits MurD with an IC50 value of 15 mM indicating a weak inhibition. Both peptides show a correlation between an increase in concentration versus an increase in inhibition values
