The lantibiotic mersacidin is a strong inducer of the cell wall stress response of Staphylococcus aureus [PDF]

open access: yes, 2008
Background The lantibiotic mersacidin is an antimicrobial peptide of 20 amino acids that is ribosomally produced by Bacillus sp. strain HIL Y-85,54728. Mersacidin acts by complexing the sugar phosphate head group of the peptidoglycan precursor lipid II ...

Biomarkers for Radiation Pneumonitis Using Noninvasive Molecular Imaging [PDF]

open access: yes, 2016
Our goal is to develop minimally invasive biomarkers for predicting radiation-induced lung injury before symptoms develop. Currently, there are no biomarkers that can predict radiation pneumonitis.

Characterization of a Multipeptide Lantibiotic Locus in Streptococcus pneumoniae

open access: yesmBio, 2016
Bacterial communities are established through a combination of cooperative and antagonistic interactions between the inhabitants. Competitive interactions often involve the production of antimicrobial substances, including bacteriocins, which are small ...

Nano-engineering the Antimicrobial Spectrum of Lantibiotics: Activity of Nisin against Gram Negative Bacteria

open access: yesScientific Reports, 2017
Lantibiotics, bacteria-sourced antimicrobial peptides, are very good candidates for effective and safe food additives. Among them, nisin is already approved by the EU and FDA, and has been used in food preservation for the past 40 years.

Bacteriocins from lactic acid bacteria: purification, properties and use as biopreservatives

open access: yesBrazilian Archives of Biology and Technology, 2007
Biopreservation systems in foods are of increasing interest for industry and consumers. Bacteriocinogenic lactic acid bacteria and/or their isolated bacteriocins are considered safe additives (GRAS), useful to control the frequent development of ...

Characterization of the Lactococcus lactis Nisin A Operon Genes nisP, Encoding a Subtilisin-Like Serine Protease Involved in Precursor Processing, and nisR, Encoding a Regulatory Protein Involved in Nisin Biosynthesis [PDF]

open access: yes, 1993
Biosynthesis of the lantibiotic peptide nisin by Lactococcus lactis NIZO R5 relies on the presence of the conjugative transposon Tn5276 in the chromosome. A 12-kb DNA fragment of Tn5276 including the nisA gene and about 10 kb of downstream DNA was cloned
