Corn smut has undergone a specialized evolution for virulence

Smut fungi are pathogens that parasitize mainly grass plants including economically important cereals like maize. Most smut pathogens cause disease symptoms only in the flowers of their host plants. An exception is Ustilago maydis, a fungus inducing tumor formation and anthocyanin accumulation in all above ground organs of maize (Figure 1). Anthocyanin formation allows the fungus to spread efficiently in the infected tissue. It is unclear how U. maydis has acquired such a unique pathogenic lifestyle. more

Protection of [Fe]-hydrogenase

Protection of [Fe]-hydrogenase

November 26, 2018

Hydrogenase enzymes catalyze production and utilization of hydrogen gas, which is considered as a future energy carrier. Scientists at the Max Planck Institute for Terrestrial Microbiology in Marburg and a collaborator at the Max Planck Institute for Biophysics discovered that [Fe]-hydrogenase is protected by conformational change of the protein. This finding is crucial for future application of hydrogenases and for understanding the catalytic mechanism of this enzyme. more

Type IV effector complexes: components of the last elusive CRISPR-Cas type

Bacteria utilize CRISPR-Cas systems to defend themselves against viral attacks. Six major CRISPR-Cas Types have been classified based on the presence of signature proteins.  Five of these six types are characterized well. Scientists of the Max Planck Society have now uncovered the components of the elusive type IV system, which include a novel CRISPR-RNA nuclease. The funcional roles of these discovered Type IV effector complexes are suggested to be found outside of viral defense. more

World’s smallest chemical reactor – Built from a single protein inside bacteria

In a living cell, hundreds to thousands different chemical reactions take place in parallel. However, many chemical reactions produce reactive or toxic compounds that could harm or even kill a cell. How do organisms protect themselves against such toxic intermediates? Now, scientists from the Max Planck Society discovered that some cells produce proteinaceous nano-reactors inside which they perform hazardous chemical reactions. more
