Background: Reversible lysine acetylation of proteins is ubiquitous in actinomycetales. Results: Arginine and cysteine allosterically regulate the protein lysine acetyltransferase Micau_1670 in Micromonospora aurantiaca.
Conclusion:The amino acid-binding domain is fused to GCN5-related acetyltransferases, conferring amino acid-induced allosteric regulation to these enzymes. Significance: Activities mediated by amino acids in these acetyltransferases directly link amino acid metabolism to cellular acetylation of proteins.
We developed a novel colorimetric method for rapid detection of biogenic amines based on arylalkylamine N-acetyltransferase (aaNAT). The proposed method offers distinct advantages including simple handling, high speed, low cost, good sensitivity and selectivity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
