Article Synopsis
  • CHKA is a key player in cell metabolism and is linked to cancer and immune function, but developing effective inhibitors has been challenging.
  • Researchers discovered that CHKA is an off-target for specific inhibitors, which helps clarify previous inconsistencies in related studies.
  • Modulating CHKA affects immune responses, particularly B-cell maturation and IgG secretion, indicating its significant role in immune signaling.

Peripheral modification is often the main approach to optimize natural products for improved biological activity or desired physicochemical properties. This procedure inevitably increases molecular weight, often accompanied by undesired increased lipophilicity. Removing structural elements from natural products is not always tolerated.

Magnetic force microscopy (MFM) is a well-established technique in scanning probe microscopy that allows for the imaging of magnetic samples with a spatial resolution of tens of nm and stray fields down to the mT range. The spatial resolution and field sensitivity can be significantly improved by measuring in vacuum conditions. This improvement originates from the higher quality-factor (Q-factor) of the cantilever's oscillation in vacuum compared to ambient conditions.

Classical Zn-dependent deac(et)ylases play fundamental regulatory roles in life and are well characterized in eukaryotes regarding their structures, substrates and physiological roles. In bacteria, however, classical deacylases are less well understood. We construct a Generalized Profile (GP) and identify thousands of uncharacterized classical deacylases in bacteria, which are grouped into five clusters.
