DOI: 10.1002/jobm.202100622
Abstract: The nucleoside antibiotic toyocamycin (TM), which is produced by Streptomyces diastatochromogenes 1628, exhibits potent activity against a broad range of phytopathogenic fungi. TM was synthesized through a multi-step reaction, using guanosine triphosphate (GTP) as precursor.… read more here.

DOI: 10.1016/j.bpj.2021.01.016
Abstract: Rac1 is a small member of Rho GTPase family. One of the most important downstream effectors of Rac1 is a serine/threonine kinase, p21-activated kinase 1 (PAK1). Mutational activation of PAK1 by Rac1 has oncogenic signaling… read more here.

DOI: 10.1016/j.str.2020.12.015
Abstract: By using 31P NMR, we present evidence that the Rho family GTPase RhoA, similar to Ras GTPases, exists in an equilibrium of conformations when bound to GTP. High-resolution crystal structures of RhoA bound to the… read more here.
