Abstract
Listeria monocytogenes exhibits two ClpP isoforms (ClpP1/ClpP2) which assemble into a heterooligomeric complex with enhanced proteolytic activity. Herein, we demonstrate that the formation of this complex depends on temperature and reaches a maximum ratio of about 1 : 1 at 30 °C, while almost no complex formation occurred below 4 °C. In order to decipher the role of the two isoforms at elevated temperatures, we constructed L. monocytogenes ClpP1, ClpP2 and ClpP1/2 knockout strains and analyzed their protein regulation in comparison to the wild type (WT) strain via whole proteome mass-spectrometry (MS) at 37 °C and 42 °C. While the ΔclpP1 strain only altered the expression of very few proteins, the ΔclpP2 and ΔclpP1/2 strains revealed the dysregulation of many proteins at both temperatures. These effects were corroborated by crosslinking co-immunoprecipitation MS analysis. Thus, while ClpP1 serves as a mere enhancer of protein degradation in the heterocomplex, ClpP2 is essential for ClpX binding and functions as a gatekeeper for substrate entry. Applying an integrated proteomic approach combining whole proteome and co-immunoprecipitation datasets, several putative ClpP2 substrates were identified in the context of different temperatures and discussed with regards to their function in cellular pathways such as the SOS response. Unlike most bacteria, L. monocytogenes encodes 2 isoforms of Caseinolytic Protease P. Balogh et al. show that both proteins form a heterocomplex temperature-dependently and find protein substrate candidates with an integrated proteomic approach.![]()

Complete genome sequencing of newly isolated thermotolerant Corynebacterium glutamicum N24 provides a new insights into its thermotolerant phenotype. J Biotechnol 2017; 247:29-33.

Abstract
To understand the genetic background of thermotolerance, we determined the complete genome sequence of a thermotolerant Corynebacterium glutamicum N24 strain isolated from soil. The whole genome based phylogenetic analysis between N24 and other related species revealed that N24 diverged from other C. glutamicum strains at earlier stages. Comparisons of thermotolerance between N24 and its related species showed that N24 and Corynebacterium efficiens YS-314 have a higher thermotolerance than Corynebacterium callunae DSM 20147 and C. glutamicum KY9002. In order to understand the link between a particular genetic background and thermotolerance, we compared the genomes of these four strains by mapping their genomes onto the N24 chromosome. We then determined the genes that were conserved in the thermotolerant species. Our results indicated the specific presence of glutathione-dependent aldehyde dehydrogenase, two sortase homologs, and lipid synthesis-related genes in the genomes of thermotolerant strains, YS-314 and N24. Therefore, these genes may be responsible for the differences in their thermotolerant phenotypes.

Abstract
Listeria monocytogenes, causative agent of human listeriosis, has been isolated from a wide variety of foods including deli meats, soft cheeses, cantaloupes, sprouts and canned mushrooms. Standard control measures for restricting microbial growth such as refrigeration and high salt are often inadequate as L. monocytogenes grows quite well in these environments. In an effort to better understand the genetic and physiological basis by which L. monocytogenes circumvents these controls, a transposon library of L. monocytogenes was screened for changes in their ability to grow in 7% NaCl and/ or at 5 °C. This work identified a transposon insertion upstream of an operon, here named lstABC, that led to a reduction in growth in 7% NaCl. In-frame deletion studies identified lstC which codes for a GNAT-acetyltransferase being responsible for the phenotype. Transcriptomic and RT-PCR analyses identified nine genes that were upregulated in the presence of high salt in the ΔlstC mutant. Further analysis of lstC and the genes affected by ΔlstC is needed to understand LstC's role in salt tolerance.

Abstract
Acetobacter pasteurianus is a Gram-negative strictly aerobic bacterium that is widely used for the industrial production of vinegar. Three Acetobacter pasteurianus strains, SKU1108, NBRC 3283 and IFO 3191, have the same 16S rRNA sequence (100 % sequence identity) but show differences in thermotolerance. To clarify the relationships between phylogeny and thermotolerance of these strains, genome-wide analysis of these three strains was performed. Concatenated phylogenetic analysis of a dataset of 1864 orthologues has shown that the more thermotolerant strains, SKU1108 and NBRC 3283, are more closely related to each other than to the more thermosensitive strain, IFO 3191. In addition, we defined a dataset of 2010 unique orthologues among these three strains, and compared the frequency of amino acid mutations among them. Genes involved in translation, transcription and signal transduction are highly conserved among each unique orthologous dataset. The results also showed that there are several genes with increased mutation rates in IFO 3191 compared with the thermotolerant strains, SKU1108 and NBRC 3283. Analysis of the mutational directions of these genes suggested that some of them might be correlated with the thermosensitivity of IFO 3191. Concatenated phylogenetic analysis of these closely related strains revealed that there is a phylogenetic relationship associated with this phenotype among the thermotolerant and thermosensitive strains.

Abstract
The foodborne transmission of Listeria monocytogenes requires physiological adaptation to various conditions, including the cold, osmotic, heat, acid, alkaline, and oxidative stresses, associated with food hygiene, processing, and preservation measures. We review the current knowledge on the molecular stress adaptation responses in L. monocytogenes cells as revealed through transcriptome, proteome, genetic, and physiological analysis. The adaptation of L. monocytogenes to stress exposure is achieved through global expression changes in a large number of cellular components. In addition, the cross-protection of L. monocytogenes exposed to different stress environments might be conferred through various cellular machineries that seem to be commonly activated by the different stresses. To assist in designing L. monocytogenes mitigation strategies for ready-to-eat food products, further experiments are warranted to specifically evaluate the effects of food composition, additives, preservatives, and processing technologies on the modulation of L. monocytogenes cellular components in response to specific stresses.
