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-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 H, N and 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.
抗生素耐药性是一个日益严重的问题,也是现代医疗保健的全球性威胁。为了确保未来仍有能力治疗细菌感染,迫切需要补充传统抗生素药物的新方法。有前途的替代品之一是溶菌酶,例如细胞壁降解肽聚糖水解酶。金黄色葡萄球菌 LytM 是 M23 家族的一种 Zn 依赖性甘氨酰-甘氨酸内肽酶,是肽聚糖水解酶之一。它对金黄色葡萄球菌的肽聚糖具有特异性,使其成为抗菌研究的一个有趣目标。LytM 水解金黄色葡萄球菌的细胞壁,金黄色葡萄球菌是一种常见的病原体,具有多种耐药菌株,例如耐甲氧西林金黄色葡萄球菌(MRSA),难以治疗。在这里,我们报告了金黄色葡萄球菌 LytM N 端结构域和连接区残基 26-184 的 H、N 和 C 化学位移分配。这些共振分配可以为进一步的研究提供基础,例如阐明结构和相互作用。
