Deletion of autophagy related, ATG1 and F-box motif encoding YDR131C, together, lead to synthetic growth defects and flocculation behavior in Saccharomyces cerevisiae.

Ubiquitin proteasome system (UPS) and autophagy both pathways are involved in clearing the nonessential cellular components and also crosstalk during cellular response to normal and stress conditions. The F-box motif proteins constitute the SCF-E3 ligase complex of the UPS pathway in Saccharomyces cerevisiae and are involved in the substrate recruitment for ubiquitination. The ATG1 encoded Atg1p, a conserved serine-threonine kinase is crucial for the autophagy process.

Nitrosoarene-Catalyzed HFIP-Assisted Transformation of Arylmethyl Halides to Aromatic Carbonyls under Aerobic Conditions.

A rare metal-free nucleophilic nitrosoarene catalysis accompanied by highly hydrogen-bond-donor (HBD) solvent, 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP), organocatalytically converts arylmethyl halides to aromatic carbonyls. This protocol offers an effective means to access a diverse array of aromatic carbonyls with good chemoselectivity under mild reaction conditions. The activation of arylmethyl halides by HFIP to generate stable carbocation and autoxidation of in situ generated hydroxylamine to nitrosoarene in the presence of atmospheric O are the keys to success.
