Mutacin 1140 Lantibiotic Variants Are Efficacious Against Clostridium difficile Infection
Lantibiotics offer an untapped pipeline for the development of novel antibiotics to treat serious Gram-positive (+) infections including Clostridium difficile. Mutacin 1140 (MU1140) is a lantibiotic produced by Streptococcus mutans and acts via a novel mechanism of action, which may limit the development of resistance. This study sought to identify a lead compound for the treatment of C. diffic...
متن کاملGenetic and biochemical analysis of mutacin 1140, a lantibiotic from Streptococcus mutans.
Streptococcus mutans JH1000 and its derivatives were previously shown (J. D. Hillman, K. P. Johnson, and B. I. Yaphe, Infect. Immun. 44:141-144, 1984) to produce a low-molecular-weight, broad-spectrum bacteriocin-like inhibitory substance (BLIS). The thermosensitive vector pTV1-OK harboring Tn917 was used to isolate a BLIS-deficient mutant, DM25, and the mutated gene was recovered by shotgun cl...
متن کاملBiosynthesis and transport of the lantibiotic mutacin 1140 produced by Streptococcus mutans.
UNLABELLED Lantibiotics are ribosomally synthesized peptide antibiotics composed of an N-terminal leader peptide that is cleaved to yield the active antibacterial peptide. Significant advancements in molecular tools that promote the study of lantibiotic biosynthesis can be used in Streptococcus mutans. Herein, we further our understanding of leader peptide sequence and core peptide structural r...
متن کاملClostridium difficile Infection.
Clostridium difficile infection is a major health care challenge in terms of patient and economic consequences. For the patient, it is a morbid and sometimes a life-threatening iatrogenic complication of antibiotic treatment. In the United States, the provider's institution may face financial penalties, because the Centers for Disease Control and Prevention views this as an iatrogenic health ca...
