Collaborative Research Center SFB987: Microbial Diversity in Environmental Signal Response.
Microorganisms are omnipresent in the biosphere and provide the greatest diversity of life on our planet. They successfully colonize almost every possible ecological niche, regardless of welcoming or hostile conditions, either as highly specialized individual cells, as microbial communities or by forming complex multi-cellular structures. A key factor for their success in colonizing varying habitats is the enormous biochemical, physiological and cellular adaptation potential of microorganisms in response to countless environmental conditions and cues. By generating microbial species with unique metabolic and cellular attributes, microbial diversity is the answer to the demands of evolution. This sets the stage for their ability to adapt to changing conditions within a given ecosystem and to explore new opportunities in novel environmental settings. For most microorganisms there is only one certainty: change!

The Collaborative Research Center TRR174: Spatiotemporal dynamics of bacterial cells
This DFG-funded collaborative research center comprises 16 research groups from the Marburg and Munich areas. Its goals are to (i) elucidate the molecular mechanisms that regulate the spatiotemporal dynamics of cellular components in bacteria; (ii) extract from the experimental data conserved design principles for spatiotemporally organized systems; and, (iii) mathematically model, design, and synthesize modules that spatially organize minimal cells or cell-free systems.
Period of funding: 01.01.2017 – 31.12.2020

The Priority Programme SPP 1879: Nucleotide Second Messenger Signaling in Bacteria
This DFG-funded priority programme centers on establishing the first systematic and comprehensive strategy ever to understand all fundamental aspects of second messenger signaling in bacteria at the molecular level. Biosynthesis, turnover and functions of c-di-GMP, the “classics” cAMP and ppGpp, as well as “newcomers” such as c-di-AMP will be studied from molecular, cellular, physiological, systems-level and ecological perspectives. The research groups in the programme, in particular, focus on understanding (i) sensory inputs into second messenger signaling; (ii) specific functions and “local” signaling of second messenger-producing and degrading enzymes in bacterial species that have multiples of these enzymes; (iii) second messenger effector mechanisms and molecular targets; and, (iv) novel physiological and ecological contexts as well as evolutionary aspects reflected in the molecular biology of second messenger signaling.
Period of funding: 09.2016 – 09.2020

DFG Priority Programm SPP 1927: "Iron-Sulfur for Life"
Subtitle: [Fe]-hydrogenase: Role of iron-sulfur bonding in holoenzyme assembly and in FeGP-cofactor biosynthesis
[Fe]-hydrogenase catalyzes the reversible transfer of a hydride from H2 to methenyl-tetrahydromethanopterin which is an intermediary step in methanogenesis from H2 and CO2. The enzyme contains one iron per active site. The iron is associated with a unique iron-guanylylpyridinol (FeGP) cofactor. In many methanogens, the [Fe]-hydrogenase structural gene (hmd) is clustered with hmd-co-occurring genes (hcgA-G), which have been shown to be involved in FeGP cofactor biosynthesis. In previous studies, we have already identified the function of five of the hcg gene-products (HcgB, HcgC, HcgD, HcgE and HcgF) using structure to function strategies and biochemical assays. HcgB catalyzed guanylyl-transfer from GTP to the 4-hydroxypyridinol. HcgC is a SAM-dependent methyltransferase; HcgD is a putative iron chaperone. HcgE catalyzes the adenylylation of the carboxy group of a 6-carboxymethyl-guanylylpyridinol precursor. Subsequently the product of HcgE reacts with Cys9 of HcgF yielding a thioester and AMP. Based on chemical precedents, we propose that the thioester reacts with an iron species forming the acyl and thiolate ligands. In the next three years, we would like to identify the function of the two remaining Hcg proteins (HcgA and HcgG), both of which are predicted to be iron-sulfur proteins. For this purpose, we will - as before - employ structure to function strategies, in vitro biosynthesis and metabolite analysis of hcg knock-out mutants.

DFG Research Group FOR1680 CRISPR/Cas: "Unraveling the prokaryotic immune system"
The FOR1680 consortium teams up scientists with expertise in microbiology, bioinformatics, structural biology and mass spectrometry. Their common goal is the elucidation of a recently discovered prokaryotic immune system based on "Clustered Regularly Interspaced Short Palindromic Repeats" (CRISPR). CRISPR elements are found in the genomes of many Bacteria and nearly all Archaea and present small RNA-based mechanisms to defend the host cell against the attack of mobile genetic elements.

Synthetic Biology Community Science Project - DOE Joint Genome Institute: "COFIX GENOMICS"
Carbon dioxide (CO2) is a potent greenhouse gas that is a critical factor in global warming. At the same time CO2 is a cheap and readily available carbon source. Because chemistry lacks suitable catalysts to functionalize the CO2 molecule, there is an increasing need to understand and exploit CO2 fixing enzymes and pathways offered by Nature. The project "COFIX-GENOMICS" within the framework of the Synthetic Biology Community Science Program of the US Department of Energy (DOE) - Joint Genome Institute aims at identifying and characterizing novel CO2 fixing enzymes in microbial genomes.

LOEWE research cluster FACE2FACE - Effects of climate change, adjusting to climate change and reducing greenhouse gas emissions by 2050
Elevated atmospheric CO2 concentrations lead to increased above-ground plant growth and increased production of fine roots, as well as to changes in C and N fluxes in soils and soil aggregates. Effects of global climate change on the phylogenetic and functional diversity of rhizosphere microbial communities were repeatedly analyzed, but with inconsistent results. Reasons may be differences in the experimental conditions (e.g., related to soil type, composition of plant communities, climate), but also in the sensitivity of the methods used for analysis. This workpackage of FACE2FACE aims to assess the effects of an increase in atmospheric CO2 concentration and air temperature on the diversity and activity of microbial communities in agricultural soils pertaining to pastureland, viticulture and horticulture. The research will be performed using cultivation-independent molecular ecology techniques, in particular next-generation sequencing of total RNA.

MIT International Science and Technology Initiatives: Spatial Order and Collective Cell Behavior in Bacterial Biofilms
Biofilms exist on almost every wet terrestrial surface and are believed to be the most abundant form of bacterial life outside the oceans. The control and suppression of biofilm-mediated infections is difficult because conventional antibiotics become inefficient or even fail completely when bacteria organize in a biofilm community, where they are protected by an extracellular gel-like matrix. Yet, in spite of intense research efforts and considerable progress over the past decades, cellular organization and communication in biofilms remain poorly understood theoretically due to a lack of quantitative models that capture the complex interplay between physical, biological and chemical processes. The proposed research aims to contribute towards a better understanding of bacterial biofilms by combining detailed mathematical and numerical modeling, performed in the Dunkel group (MIT Mathematics), with state-of-the-art microscopy data produced by the Drescher lab (Max Planck Institute for Terrestrial Microbiology).
