Abstract

Regulation of rice seed germination has been shown to mainly occur at post-transcriptional levels, of which the changes on proteome status is a major one. Lysine acetylation and succinylation are two prevalent protein post-translational modifications (PTMs) involved in multiple biological processes, especially for metabolism regulation. To investigate the potential mechanism controlling metabolism regulation in rice seed germination, we performed the lysine acetylation and succinylation analyses simultaneously. Using high-accuracy nano-LC-MS/MS in combination with the enrichment of lysine acetylated or succinylated peptides from digested embryonic proteins of 24 h after imbibition (HAI) rice seed, a total of 699 acetylated sites from 389 proteins and 665 succinylated sites from 261 proteins were identified. Among these modified lysine sites, 133 sites on 78 proteins were commonly modified by two PTMs. The overlapped PTM sites were more likely to be in polar acidic/basic amino acid regions and exposed on the protein surface. Both of the acetylated and succinylated proteins cover nearly all aspects of cellular functions. Ribosome complex and glycolysis/gluconeogenesis-related proteins were significantly enriched in both acetylated and succinylated protein profiles through KEGG enrichment and protein-protein interaction network analyses. The acetyl-CoA and succinyl-CoA metabolism-related enzymes were found to be extensively modified by both modifications, implying the functional interaction between the two PTMs. This study provides a rich resource to examine the modulation of the two PTMs on the metabolism pathway and other biological processes in germinating rice seed.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Compared with malonate, itaconate is a relatively weak competitive inhibitor of SDH.

    “However, it must also be noted that, compared with malonate, itaconate is a relatively weak competitive inhibitor of SDH47,49, which raised the question as to whether any additional mechanisms could contribute to the anti-inflammatory effects of itaconate.”
  • A range of proteins regulating T cell function are sensitive to covalent modification by DMF, including PKCθ.

    “By employing a proteomic approach the authors discovered a range of proteins which regulate T cell function that are sensitive to covalent modification by DMF including protein kinase C θ (PKCθ).”
  • DMF but not MMF inhibits activation of human and mouse T cells.

    “Blewett and colleagues (2016) demonstrated that dimethyl fumarate (DMF), a potent electrophile which is currently used to treat psoriasis and relapse-remitting MS, but not MMF inhibited the activation of human and mouse T cells 49.”
  • DMF blocks the association of PKCθ with CD28 and T cell activation.

    “Mechanistically, DMF blocked the association of PKCθ with the costimulatory receptor CD28 and T cell activation.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
