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.
UV radiation induces two major types of DNA lesions, cyclobutane pyrimidine dimers (CPDs) and 6-4 pyrimidine-pyrimidine photoproducts, which are both primarily repaired by nucleotide excision repair (NER). Here, we investigated how chronic low-dose UV (CLUV)-induced mutagenesis occurs in rad14Δ NER-deficient
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
Mitochondrial succinate dehydrogenase (SDH) is an essential complex of the electron transport chain and tricarboxylic acid cycle. Mutations in the human SDH subunit D frequently lead to paraganglioma (PGL), but the mechanistic consequences of the majority of SDHD polymorphisms have

The ribonuclease (RNase) H class of enzymes degrades the RNA component of RNA:DNA hybrids and is important in nucleic acid metabolism. RNase H2 is specialized to remove single ribonucleotides [ribonucleoside monophosphates (rNMPs)] from duplex DNA, and its absence in budding
Base editors (BEs) are RNA-guided CRISPR-Cas-derived genome editing tools that induce single-nucleotide changes. The limitations of current BEs lie in their low precision (especially when multiple target nucleotides of the deaminase are present within the activity window) and their restriction
