01/03/2019Lysine crotonylation is a new posttranslational modification (PTM) type identified on histones which is enriched on active gene promoters or potential enhancers in mammalian cell genomes However the function of lysine crotonylation in the cancer process is not known Intriguingly we found that lysine crotonylation expression is down

To understand the putative biological functions of the CpIAA genes involved in fruit development and ripening quantitative real-time PCR was used to test the expression profiling of CpIAA genes at different stages Furthermore an IAA treatment significantly delayed the ripening process in papaya fruit at the early stages The expression changes of CpIAA genes in ACC and 1-MCP treatments

05/06/2017Protein lysine acetylation is a prevalent post-translational modification that plays pivotal roles in various biological processes in both prokaryotes and eukaryotes Aspergillus flavus as an aflatoxin-producing fungus has attracted tremendous attention due to its health impact on agricultural commodities Here we performed the first lysine-acetylome mapping in this filamentous fungus using

Post-translational modification of proteins by lysine acetylation plays important regulatory roles in living cells The budding yeast Saccharomyces cerevisiae is a widely used unicellular eukaryotic model organism in biomedical research S cerevisiae contains several evolutionary conserved lysine acetyltransferases and deacetylases However only a few dozen acetylation sites in S cerevisiae

Introduksjon Post-translation modifisering (PTM) av lysin en kovalent modifikasjon involvert i ulike biologiske prosesser er en effektiv strategi for ke det strukturelle og funksjonelle mangfoldet av proteiner 1 2 Hittil har et stort antall PTM inkludert fosforylering ubiquitinering acetylering og succinylering blitt identifisert i bde eukaryotiske og prokaryote arter 3 4 5

To investigate the impacts of lysine acetylation on Schistosoma japonicum (S japonicum) development and sexual maturation we used immunoaffinity-based acetyllysine peptide enrichment combined with mass spectrometry (MS) to perform the first comparative analysis of proteome-wide lysine acetylation in both and male juvenile (18 days post infection 18 dpi) and adult (28 dpi

The method consists of labeling N-termini and lysine -amino groups through reductive amination using acetaldehyde This allows isotope labeling using pairs of either 2H/1H or 13C/12C without mass spectrum overlap Our labeling procedure which is significantly different than that developed for dimethylation can be completed with little trace of partial ethylation non-labeled peptides

Lysine crotonylation on histones is a recently identified post-translational modification that has been demonstrated to associate with active promoters and to directly stimulate transcription Given that crotonyl-CoA is essential for the acyl transfer reaction and it is a metabolic intermediate widely localized within the cell we postulate that lysine crotonylation on nonhistone proteins

Bartlett et al demonstrate that serine ADP-ribosylation and proximal phosphorylation and acetylation are mutually exclusive at the N-terminal tails of core histones They also expand the repertoire of ADP-ribosylation target residues by providing evidence for tyrosine ADP-ribosylation on
