The corresponding 4-acetylamino-2-thiophenecarboxylic acids or their esters were produced by the action of reduced iron on solutions of 4-nitro-2-thiophenecarboxylic acid, its derivatives, or their esters in a mixture of acetic acid and acetic anhydride. Esters of 5-acetylamino-2-thiophene...

Cobalt(II) chloride hexahydrate (CoCl 2·6H 2O) efficiently catalyzes the acetylation of alcohols with AcOH in high yields. This protocol is also effective with other carboxylic acids, trifluoroacetic acid, propanoic acid, phenylacetic acid and benzoic acid, affording the corresponding acylated product...

scenario.74Most importantly, Pan showed that the cleavage of the dithiolane ring by the enamine required electrophilic catalysis. In the model system this could be accomplished by S-methylation, while on the enzymes the reaction presumably uses an acid catalyst such as a histidinium ion, ...
fraction. Mitochondrial proteins accounted for 59% of all proteins and 64% of all acetylation sites identified; the proteins were strongly associated with fatty acid metabolism enzymes, oxidative phosphorylation and the tri-carboxylic acid cycle. These proteins usually contained more than one acetylation...
EIN2 has a large (B800 amino acid) CEND, and its N-terminal region has a high degree of sequence identity with the NRAMP family of metal transporters16. In the absence of ethylene gas, EIN2 is localized to the ER membrane and interacts with ETR1 (ref. 17) and two F-box proteins ...
