Structures of NS5 Methyltransferase from Zika Virus

Cell Reports, 2016
The Zika virus (ZIKV) poses a major public health emergency. To aid in the development of antivirals, we present two high-resolution crystal structures of the ZIKV NS5 methyltransferase: one bound to S-adenosylmethionine (SAM) and the other bound to SAM ...

Rho GTPases as Key Molecular Players within Intestinal Mucosa and GI Diseases

Cells, 2021
Rho proteins operate as key regulators of the cytoskeleton, cell morphology and trafficking. Acting as molecular switches, the function of Rho GTPases is determined by guanosine triphosphate (GTP)/guanosine diphosphate (GDP) exchange and their lipidation

A theoretical estimate for nucleotide sugar demand towards Chinese Hamster Ovary cellular glycosylation [PDF]

, 2016
Glycosylation greatly influences the safety and efficacy of many of the highest-selling recombinant therapeutic proteins (rTPs). In order to define optimal cell culture feeding strategies that control rTP glycosylation, it is necessary to know how ...

Structural Insights into the Regulation Mechanism of Small GTPases by GEFs

Molecules, 2019
Small GTPases are key regulators of cellular events, and their dysfunction causes many types of cancer. They serve as molecular switches by cycling between inactive guanosine diphosphate (GDP)-bound and active guanosine triphosphate (GTP)-bound states ...

Synthesis of Guanosine 5'-Diphosphate.

Chemical and Pharmaceutical Bulletin, 1959
Guanosine 5'-diphosphate was synthesized from guanosine 5'-monophosphate by the reaction of benzyl hydrogen phosphoramidate, followed by the catalytic hydrogenolysis, in a yield of 38%. The effect of water in the reaction media and correlation of the yield with the amount of reagents are discussed.

Regulation of Bacteriophage λ Development by Guanosine 5′-Diphosphate-3′-diphosphate

Virology, 1999
On infection of its host, Escherichia coli, bacteriophage lambda can follow one of two alternative developmental pathways: lytic or lysogenic. Here we demonstrate that the "lysis-versus-lysogenization" decision is influenced by guanosine tetraphosphate (ppGpp), a nucleotide that is synthesized in E. coli cells in response to amino acid or carbon source

Ligand-Specific Regulation of the Endogenous Mu-Opioid Receptor by Chronic Treatment with Mu-Opioid Peptide Agonist [PDF]

, 2013
Since the discovery of the endomorphins (EM), the postulated endogenous peptide agonists of the mu-opioid receptors, several analogues have been synthesized to improve their binding and pharmacological profiles.

RNA‐Micelles as Self‐Assembling Structures for Efficient Co‐Delivery of Synergistic siRNA and Nucleoside Analogues to Treat CRC Lung Metastasis

Advanced Functional Materials, EarlyView.
Two kinds of self‐assembled RNA micelles were used to co‐deliver synergistic siRNA and nucleoside analogues for the treatment of colorectal cancer lung metastases. Near‐complete elimination of lung cancer metastases was confirmed in an orthotopic lung metastasis model constructed using human colorectal cancer lung metastases patient surgical samples to
