The present invention comprises the murM and murN genes expressed from the
Streptococcus pneumoniae
murMN operon, the murM and murN proteins encoded by the respective genes as well as oligonucleotides to amplify the genes. MurM and MurN are proteins involved in forming a branched muropeptide structure in
S. pneumoniae
peptidoglycan which is associated with β-lactam antibiotic resistance in the bacteria. Also provided are methods for identifying inhibitors of MurM or MurN along with methods of treating subjects suffering from a
S. pneumoniae
infection by administering MurM or MurN inhibitors in conjunction with a β-lactam antibiotic.
本发明包括从肺炎链球菌中表达的 murM 和 murN
基因。
肺炎链球菌
murMN操作子表达的murM和murN
基因、各
基因编码的murM和murN蛋白以及扩增
基因的寡核苷酸。MurM 和 MurN 蛋白参与形成肺炎链球菌的支链肽结构。
肺炎双球菌
肽聚糖结构,该结构与该细菌的 β-内酰胺类抗生素耐药性有关。此外,还提供了鉴定 MurM 或 MurN
抑制剂的方法,以及治疗肺炎双球菌感染者的方法。
肺炎链球菌
MurM或MurN
抑制剂以及β-内酰胺类抗生素的方法。
