(1)H, (13)C, and (15)N NMR chemical shift assignment of LytM N-terminal domain (residues 26–184)

Antibiotic resistance is a growing problem and a global threat for modern healthcare. New approaches complementing the traditional antibiotic drugs are urgently needed to secure the ability to treat bacterial infections also in the future. Among the promising alternatives are bacteriolytic enzymes, such as the cell wall degrading peptidoglycan hydrolases. Staphylococcus aureus LytM, a Zn(2+)-dependent glycyl-glycine endopeptidase of the M23 family, is one of the peptidoglycan hydrolases. It has a specificity towards staphylococcal peptidoglycan, making it an interesting target for antimicrobial studies. LytM hydrolyses the cell wall of S. aureus, a common pathogen with multi-resistant strains that are difficult to treat, such as the methicillin-resistant S. aureus, MRSA. Here we report the (1)H, (15)N and (13)C chemical shift assignments of S. aureus LytM N-terminal domain and linker region, residues 26–184. These resonance assignments can provide the basis for further studies such as elucidation of structure and interactions.
