Patterns of protein synthesis in the budding yeast cell cycle: variable or constant?
Eun-Gyu No, Heidi M Blank and Michael Polymenis
Proteins are the principal macromolecular constituent of proliferating cells, and protein synthesis is viewed as a primary metric of cell growth. While there are celebrated examples of proteins whose levels are periodic in the cell cycle (e.g., cyclins), the concentration of most proteins was not thought to change in the cell cycle, but some recent results challenge this notion. The ‘bulk’ protein is the focus of this article, specifically the rate of its synthesis, in the budding yeast Saccharomyces cerevisiae.
Ribose 5-phosphate: the key metabolite bridging the metabolisms of nucleotides and amino acids during stringent response in Escherichia coli?
Paulina Katarzyna Grucela1, Tobias Fuhrer2, Uwe Sauer2, Yanjie Chao3 and Yong Everett Zhang1
Here we propose the metabolite ribose 5’-phosphate as the key link between nucleotide and amino acid metabolisms and a working model integrating both the transcriptional and metabolic effects of (p)ppGpp on E. coli physiological adaptation during the stringent response.
Flagellated bacterial porter for in situ tumor vaccine
Haiheng Xu1, Yiqiao Hu1, 2 and Jinhui Wu1, 2, 3
Cancer immunotherapy, which use the own immune system to attack tumors, are increasingly popular treatments. But, due to the tumor immunosuppressive microenvironment, the antigen presentation in the tumor is limited. Recently, a growing number of people use bacteria to stimulate the body's immunity for tumor treatment due to bacteria themselves have a variety of elements that activate Toll-like receptors. Here, we discuss the use of motility of flagellate bacteria to transport antigens to the tumor periphery to activate peritumoral dendritic cells to enhance the effect of in situ tumor vaccines.
The rise of Candida auris: from unique traits to co-infection potential
Nadine B. Egger1,§, Katharina Kainz1,§, Adina Schulze1, Maria A. Bauer1, Frank Madeo1-3 and Didac Carmona-Gutierrez1
Candida auris is a multidrug resistant (MDR) fungal pathogen with a crude mortality rate of 30-60%. First identified in 2009, C. auris has been rapidly rising to become a global risk in clinical settings and was declared an urgent health threat by the Centers for Disease Control and Prevention (CDC). A concerted global action is thus needed to successfully tackle the challenges created by this emerging fungal pathogen. In this brief article, we underline the importance of unique virulence traits, including its easy transformation, its persistence outside the host and its resilience against multiple cellular stresses, as well as of environmental factors that have mainly contributed to the rise of this superbug.
A hundred spotlights on microbiology: how microorganisms shape our lives
Didac Carmona-Gutierrez1, Katharina Kainz1, Andreas Zimmermann1, Sebastian J. Hofer1, Maria A. Bauer1, Christoph Ruckenstuhl1, Guido Kroemer2-4 and Frank Madeo1,5,6
Viral, bacterial, fungal and protozoal biology is of cardinal importance for the evolutionary history of life, ecology, biotechnology and infectious diseases. Various microbiological model systems have fundamentally contributed to the understanding of molecular and cellular processes, including the cell cycle, cell death, mitochondrial biogenesis, vesicular fusion and autophagy, among many others. Microbial interactions within the environment have profound effects on many fields of biology, from ecological diversity to the highly complex and multifaceted impact of the microbiome on human health. Also, biotechnological innovation and corresponding industrial operations strongly depend on microbial engineering. With this wide range of impact in mind, the peer-reviewed (...)
Yeast goes viral: probing SARS-CoV-2 biology using S. cerevisiae
Brandon Ho1, Raphael Loll-Krippleber1 and Grant W. Brown1
The budding yeast Saccharomyces cerevisiae has long been an outstanding platform for understanding the biology of eukaryotic cells. Robust genetics, cell biology, molecular biology, and biochemistry complement deep and detailed genome annotation, a multitude of genome-scale strain collections for functional genomics, and substantial gene conservation with Metazoa to comprise a powerful model for modern biological research. Recently, the yeast model has demonstrated its utility in a perhaps unexpected area, that of eukaryotic virology. Here we discuss three innovative applications of the yeast model system to reveal functions and investigate variants of proteins encoded by the SARS-CoV-2 virus.
Murals meet microbes: at the crossroads of microbiology and cultural heritage
Maria A. Bauer1, Katharina Kainz1, Christoph Ruckenstuhl1, Frank Madeo1-3 and Didac Carmona-Gutierrez1
This article comments on the duality of microorganisms in the conservation and restoration of cultural heritage, which encompasses the negative impact of damaging microorganisms and recent advances in using specific microorganisms and microbial-based technologies for cultural heritage preservation.
Urm1, not quite a ubiquitin-like modifier?
Lars Kaduhr1, Cindy Brachmann1, Keerthiraju Ethiraju Ravichandran2,3, James D. West4, Sebastian Glatt2 and Raffael Schaffrath1
This article comments on work published by Brachmann et al. (Redox Biol, 2020), which studied urmylation of the yeast 2-Cys peroxiredoxin Ahp1, uncovering that promiscuous lysine target sites and specific redox requirements determine the Urm1 acceptor activity of the peroxiredoxin.
It takes four to tango: the cooperative adventure of scientific publishing
February 21, 2025
This Editorial is the 500th article published in Microbial Cell, a journey that started in 2014 and has seen the journal grow steadily and maintain itself as a respected community platform. The foundation that has allowed for and driven this development – as for any responsible journal – is composed of four essential pillars: the readers, the authors, the editors and the referees.
