Systematic Analysis of the Lysine Crotonylome and multiple PTM analysis (acetylation, succinylation and crotonylation) in Candida albicans

ABSTRACT: LC-MS/MS was used to carry out the analysis of the crotonylome in C. albicans (Candida albicans) comprehensively in our study. Generally, 5242 specific crotonylated sites of 1584 crotonylated proteins were detected among 9038 proteins in C. albicans. The crotonylome involved in the regulation of metabolism through the bioinformatics analysis. Moreover, the crotonylated proteins related to biosynthesis and carbon metabolism were prevalence phenomenon. Moreover, a universal rule were found in crotonylated motifs: D/E were found in the position (+1, +2 or +3) and K/R were found in the position (+5 or +6) of the residue; A/E/F/G/P/W/Y were found in the -1 position and A/K/R were found in the position (-5, -6, -7 or -8) of the residue. As far as we know, crotonylated histone sites that screened in C. albicans of this study have not been reported before. Furthermore, a variety of connections in PPI (protein-protein interaction network) of ribosome, oxidative phosphorylation, nucleus and proteasome were modified by acetylation, succinylation and crotonylation. Sir2 inhibitor AK-1 was able to promote histone lysine crotonylation and non-histone lysine crotonylation.

Project description:Lysine crotonylation of histone proteins is a newly identified post-translational modification with diversified cellular functions. However, there’s few reports on lysine crotonylation of non-histone proteins in fruit plant cells. By using high-resolution LC-MS coupled with highly sensitive specific immune-affinity antibody analysis, a whole crotonylation proteome analysis of Dendrobium huoshanese was performed. In total, 1,591 proteins with 4,725 lysine crotonylation sites were found, among them eleven conserved motifs have been identified. Bioinformatic analysis linked crotonylated proteins to multiple metabolic pathways, including secondary metabolites biosynthesis, transport and catabolism; energy production and conversion; carbohydrate transport and metabolism; and translation, ribosomal structure and biogenesis.

Global Proteomic Analysis of Lysine crotonylation in The Plant Pathogen Botrytis cinerea

Project description:Lysine crotonylation (Kcr), a recently discovered post-translational modification, plays a key role in the regulation of diverse cellular processes. Botrytis cinerea is a destructive necrotrophic fungal pathogen distributed worldwide with broad ranging hosts. However, the functions of Kcr are unknown in B. cinerea or any other plant fungal pathogens. Here, we comprehensively evaluated the crotonylation proteome of B. cinerea and identified 3967 Kcr sites in 1041 proteins, of which contained in 9 types of modification motifs. Our results show that although the crotonylation were largely conserved, different organisms contained distinct crotonylated proteins with unique functions. Bioinformatic analysis demonstrated that the majority of crotonylated proteins were distributed in cytoplasm (35%), mitochondria (26%) and nucleus (22%). The identified proteins were found to be involved in various metabolic and cellular processes, such as cytoplasmic translation and structural constituent of ribosome. Particularly, 26 crotonylated proteins participated in the pathogenicity of B. cinerea, suggesting a significant role for Kcr in this process. Protein interaction network analysis demonstrated that a mass of protein interactions are regulated by crotonylation. These data represent the ﬁrst report of the crotonylome of B. cinerea and provide a good foundation for further explorations of the role of Kcr in plant fungal pathogens.

Crotonylation versus acetylation in PaACL-silenced corollas in petunia

Project description:Protein acetylation and crotonylation are important post-translational modifications (PTMs) of lysine. In animal cells, histone lysines are crotonylated or acetylated depends on the relative intracellular concentrations of crotonyl-CoA and acetyl-CoA, and adding crotonate to cell cultures, or reducing the intracellular levels of acetyl-CoA, leads to an increase in histone crotonylation through the direct production of crotonyl-CoA. However, in plant the relationship of acetylation and crotonylation and the effect of the concentration of acetyl-CoA on protein crotonylation were not well known. Our previous study showed that PhACL silencing changed the content of acetyl CoA in petunia corollas. In this study, we performed a global crotonylation proteome analysis of petunia (Petunia hybrida) and found that protein crotonylation have close relationship with protein acetylation and the protein with more crotonylation sites often had more acetylation sites. Crotonylated proteins and acetylated proteins enriched in many common KEGG pathway. However, PhACL silencing resulted in different KEGG pathway enrichment of proteins with different level of crotonylated sites and acetylated sites. Cytoplasm non-histone lysine crotonylation may not depend on the concentrations of acetyl-CoA in petunia corollas. There was a positive correlation between crotonylome and acetylome expression levels in corollas of PhACL-silenced plants and control.

First comprehensive proteome analysis of lysine crotonylation in Streptococcus agalactiae, a pathogen causing meningoencephalitis in teleosts

Project description:In Homo sapiens, Streptococcus agalactiae is a common colonizer of the rectovaginal tract and a fundamental cause of neonatal and non-pregnant adults infectious diseases. It also causes infectious disease in fish which compromises food safety as well as possesses a zoonotic risk. Lysine crotonylation (Kcr) is a type of histone post-translational modifications discovered in 2011. Kcr dynamics are involved in active gene promoters and potential enhancers in yeast and mammalian. However, lysine crotonylation in S. agalactiae has not yet been studied. In the present study, we conducted the first proteome-wide profiling of Kcr in S. agalactiae and identified 241 Kcr sites on 675 proteins, representing the Kcr event in S. agalactiae. Bioinformatics analysis showed that 164 sequences were matched to a total of six definitively conserved motifs, and many of them were significantly enriched in metabolic processes, cellular process, and single-organism processes. Moreover, we found four crotonylation modified proteins predicted as quorum sensing system and virulence factors, which indicate the important role of PTM on bacterial QS system and virulence. These data represent the first report of a global crotonylation proteome and provide a promising starting point for further functional research of crotonylation in bacterial virulence in S. agalactiae.

Proteome-wide analysis of Lysine 2-Hydroxyisobutyrylation in Candida albicans

Project description:Candida albicans is the most common human fungal pathogen, causing diseases ranging from mucosal to systemic infections for both immunocompetent and immunocompromised individuals. Lysine 2-hydroxyisobutyrylation is a highly conserved posttranslational modification found in a wide variety of organisms. In this study, we survey the biological impact of 2-hydroxyisobutyrylation on lysine residuals (Khib) in C. albicans. Using an antibody-enrichment approach along with the traditional LC-MS/MS method, the pattern of Khib-modified proteins and sites were analyzed in one wild type strain of C. albicans. We identified 1438 Khib-modified proteins with 6659 modified sites in this strain, and a more detailed bioinformatics analysis indicated that the Khib-modified proteins are involved in a wide range of cellular functions with diverse subcellular locations. Functional enrichment analysis featured several prominent functional pathways, including ribosome, biosynthesis of antibiotics, biosynthesis of secondary metabolites, biosynthesis of amino acids and carbon metabolism – of which the ribosome pathway is the most affected pathway. Even when compared with the reported lysine acetylation (Kac) and succinylation (Ksuc), the Khib-modified sites on ribosomal proteins remained the highest for C. albicans. These bioinformatic results suggest that 2-hydroxyisobutyrylation may play an indispensable role in the regulation of the ribosomal biogenesis and protein translation. Confirmation at the biochemical level would enable us to resolve physiological and pathogenic roles of PTM in C. albicans.

Crotonylome profiling reveals extensive lysine crotonylation in common wheat

Project description:Histone lysine crotonylation (Kcr) is a newly discovered protein post-translational modification (PTM), which was detected from yeast to humans and is mainly related with active transcription. With the development of proteomics technologies, high abundance of non-histone proteins modified by Kcr was also found recently. Here, we first report that lysine Kcr also occurs on cytoplasmic and mitochondrial proteins in common wheat (Triticum aestivum L.). We identified 4,696 Lys-acetylated sites on 1,726 proteins which involved in a wide variety of biological processes, such as chromatin-associated processes, Calvin-Benson cycle, glycolysis, protein metabolism and transport, which representing the largest dataset of lysine acylation proteome reported in the plant kingdom. Interestingly, 98 proteins were involved in multiple processes of photosynthesis, suggesting an important role of lysine Kcr in processes. In addition, 21 potentially specific Kcr motifs in wheat were detected. The protein interaction network analysis revealed that diverse interactions are modulated by protein Kcr. The overlap between Kcr and acetylation (Kac) indicated that they may coordinately regulate the function of some proteins in common wheat. Futhermore, comparative analysis indicated that lysine Kcr is conserved between common wheat and Nicotiana tabacum. Taken together, this study provided the first global survey of Kcr in wheat, making a promising starting point for further functional analysis of Kcr in plants.

Global involvement of lysine crotonylation in protein modification and transcription regulation in rice

Project description:Lysine crotonylation (Kcr) is a newly discovered post-translational modification (PTM) existing in mammals. A global crotonylome analysis was undertaken in rice (Oryza sativa L. japonica) using high accuracy nano-LC-MS/MS in combination with crotonylated peptide enrichment. A total of 1,265 lysine crotonylation sites were identified on 690 proteins in rice seedlings. Subcellular localization analysis revealed that 51% of the crotonylated proteins identified were localized in chloroplasts. The photosynthesis-associated proteins were also mostly enriched in total crotonylated proteins. In addition, a genomic localization analysis of histone Kcr by ChIP-seq was performed to assess the relevance between histone Kcr and the genome. Of the 10,923 identified peak regions, the majority (86.7%) of the enriched peaks were located in gene body, especially exons. Furthermore, the degree of histone Kcr modification was positively correlated with gene expression in genic regions. Compared with other published histone modification data, the Kcr was co-located with the active histone modifications. Interestingly, histone Kcr facilitated expression of genes with existing active histone modifications. In addition, 77% of histone Kcr modifications overlapped with DNase hypersensitive sites (DHSs) in intergenic regions of the rice genome, and might mark other cis-regulatory DNA elements which are different from IPA1, a transcription activator in rice seedlings. Overall, our results provide a comprehensive understanding of the biological functions of the crotonylome and new active histone modification in transcriptional regulation in plants.
