ECD-like peptide fragmentation at atmospheric pressure [PDF]

open access: yesInternational Journal of Mass Spectrometry, 2012
Fragmentation of multiply-charged peptide ions via interaction with products of gas discharge at atmospheric pressure conditions was studied using ion mobility separation - fragmentation cell - linear ion trap mass spectrometer. The observed fragmentation spectra mainly consisted of c- type ions that are specific to electron capture dissociation ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Characterization of Trypsin-Like Protease of Lactobacillus plantarum FNCC 0270

open access: yesHayati Journal of Biosciences, 2014
Trypsin is an enzyme that has a unique mechanism of cutting peptide bonds specifically at the carboxyl side of lysine or arginine amino acids, with another amino acid.

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

open access: yesFEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

Predicting peptide structures in native proteins from physical simulations of fragments. [PDF]

open access: yesPLoS Computational Biology, 2009
It has long been proposed that much of the information encoding how a protein folds is contained locally in the peptide chain. Here we present a large-scale simulation study designed to examine the extent to which conformations of peptide fragments in ...

A predator-prey interaction between a marine Pseudoalteromonas sp. and Gram-positive bacteria [PDF]

open access: yes, 2020
Predator-prey interactions play important roles in the cycling of marine organic matter. Here we show that a Gram-negative bacterium isolated from marine sediments (Pseudoalteromonas sp.

Lipid-Induced β-Amyloid Peptide Assemblage Fragmentation [PDF]

open access: yesBiophysical Journal, 2006
Alzheimer's disease is the most common cause of dementia and is widely believed to be due to the accumulation of beta-amyloid peptides (Abeta) and their interaction with the cell membrane. Abetas are hydrophobic peptides derived from the amyloid precursor proteins by proteolytic cleavage.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Elucidating functional epitopes within the N-terminal region of malaria transmission blocking vaccine antigen Pfs230

open access: yesnpj Vaccines, 2022
Pfs230 is a leading malaria transmission blocking vaccine (TBV) candidate. Comprising 3135 amino acids (aa), the large size of Pfs230 necessitates the use of sub-fragments as vaccine immunogens. Therefore, determination of which regions induce functional

A novel antibacterial peptide derived from Crocodylus siamensis haemoglobin hydrolysate induces membrane permeabilization causing iron dysregulation, oxidative stress and bacterial death [PDF]

open access: yes, 2017
Aims A novel antibacterial peptide from Crocodylus siamensis haemoglobin hydrolysate (CHH) was characterized for antimicrobial activity. Methods and Results CHHs were hydrolysed for 2 h (2 h-CHH), 4 h (4h-CHH), 6 h (6 h-CHH) and 8 h (8 h-CHH). The
