A naturally occurring L-amino acid that interferes with L-arginine-utilizing enzymes due to its structural similarity. It is a selective inhibitor of inducible nitric oxide synthase (iNOS). Overproduction of NO by iNOS plays a crucial role in the pathophysiology of septic shock and chronic inflammation.
Canavanine is a naturally occurring L-amino acid that interferes with L-arginine-utilizing enzymes due to its structural similarity. It is a selective inhibitor of inducible nitric oxide synthase (iNOS). Overproduction of NO by iNOS plays a crucial role in the pathophysiology of septic shock and chronic inflammation.
RNA-guided nucleases of the CRISPR/Cas type can be repurposed as programmable nucleotide deaminases to mediate targeted nucleotide substitutions. Such base editors have enormous potential in genome editing, gene therapy and precision breeding. However, current editors suffer from limited specificity in

Impairment of mitochondrial protein homeostasis disrupts mitochondrial function and causes human diseases and aging, but the molecular mechanisms of protein synthesis and quality control in mammalian mitochondria are not fully understood. Here we demonstrate in human cells that misincorporation of
The uptake of drugs into cells has traditionally been considered to be predominantly via passive diffusion through the bilayer portion of the cell membrane. The recent recognition that drug uptake is mostly carrier-mediated raises the question of which drugs use

Transport along the endolysosomal system requires multiple fusion events at early and late endosomes. Deletion of several endosomal fusion factors, including the Vac1 tether and the Class C core vacuole/endosome tethering (CORVET) complex-specific subunits Vps3 and Vps8, results in a
Non-proteinogenic amino acids, such as the proline analog L-azetidine-2-carboxylic acid (AZC), are detrimental to cells because they are mis-incorporated into proteins and lead to proteotoxic stress. Our goal was to identify genes that show chemical-genetic interactions with AZC in Saccharomyces
