SARS-CoV-2 and bat RaTG13 spike glycoprotein structures inform on virus evolution and furin-cleavage effects.

Nature structural & molecular biology 2020 ๐Ÿ“Š 520

SARS-CoV-2 is thought to have emerged from bats, possibly via a secondary host. Here, we investigate the relationship of spike (S) glycoprotein from SARS-CoV-2 with...

Mechanisms of aureobasidin A inhibition and drug resistance in a fungal IPC synthase complex.

Nature communications 2025 ๐Ÿ“Š 6

The enzyme inositol phosphorylceramide (IPC) synthase is essential for survival and virulence in fungi, while absent in mammals, thus representing a potential target for antifungal...

Systemic Expression, Purification, and Initial Structural Characterization of Bacteriophage T4 Proteins Without Known Structure Homologs.

Frontiers in microbiology 2021 ๐Ÿ“Š 6

Bacteriophage T4 of Escherichia coli is one of the most studied phages. Research into it has led to numerous contributions to phage biology and biochemistry....

Structures of complete extracellular assemblies of type I and type II Oncostatin M receptor complexes.

Nature communications 2024 ๐Ÿ“Š 6

Oncostatin M (OSM) is a unique Interleukin 6 (IL-6) family cytokine that plays pivotal roles in numerous biological events by signaling via two types of...
