The common post-translational modification trans-4-hydroxy-L-proline is reversed by gut microbes with the help of hydroxyproline dehydratase (HypD), an enzyme that performs a radical chemical mechanism.
A peptide derived from BK and JC polyomavirus protein VP2/3 inhibits viral infection by targeting a binding site in the pore of polyomavirus VP1 pentamers, enabling future VP1-targeted therapeutic strategies.
Thalidomide and its derivates induce degradation of many C2H2 zinc-finger transcription factors, including SALL4, providing insight into a long-standing mystery in modern pharmacology, and starting points for future drug development.
Combined cell labelling with a bi-cistronic reporter-gene vector and gold nanorods enables short- and long-term cell tracking in vivo via multimodal imaging (multispectral optoacoustic tomography, bioluminescence, fluorescence) with high spatial resolution.
Synthetic single domain antibody libraries and a binder selection cascade encompassing ribosome and phage display enable the selection of conformation-specific binders against previously intractable membrane proteins within three weeks.
The nerve growth-repellent activity that generates spinal nerve repeat-patterning in birds and mammals is identified at the molecular level, and a similar system is revealed in adult brain grey matter.
