Article Synopsis
  • Liquid chromatography-tandem mass spectrometry (LC-MS/MS) is used to identify natural products, but the complex structures of these products make data analysis challenging.
  • A new algorithm called MassKG has been developed, which utilizes a combination of knowledge-based fragmentation and deep learning to streamline the identification of natural product structures.
  • MassKG has already compiled a vast database of known natural products and generated new potential compounds, showing superior performance in data annotation and is available online with features that improve usability for researchers.

Background: Degradation via enzymatic processes for the production of valuable β-1,3-glucooligosaccharides (GOS) from curdlan has attracted considerable interest. CBM6E functions as a curdlan-specific β-1,3-endoglucanase, composed of a glycoside hydrolase family 128 (GH128) module and a carbohydrate-binding module (CBM) derived from family CBM6.

Results: Crystallographic analyses were conducted to comprehend the substrate specificity mechanism of CBM6E.

Mouse somatic cells can be reprogrammed into induced pluripotent stem cells through a highly heterogeneous process regulated by numerous biological factors, including adenosine-to-inosine (A-to-I) RNA editing. In this study, we analyzed A-to-I RNA editing sites using a single-cell RNA sequencing (scRNA-seq) dataset with high-depth and full-length coverage. Our method revealed that A-to-I RNA editing frequency varied widely at the single-cell level and underwent dynamic changes.

Bats are considered reservoirs of many lethal zoonotic viruses and have been implicated in several outbreaks of emerging infectious diseases, such as SARS-CoV, MERS-CoV, and SARS-CoV-2. It is necessary to systematically derive the expression patterns of bat virus receptors and their regulatory features for future research into bat-borne viruses and the prediction and prevention of pandemics. Here, we performed single-nucleus RNA sequencing (snRNA-seq) and single-nucleus assay for transposase-accessible chromatin using sequencing (snATAC-seq) of major organ samples collected from Chinese horseshoe bats (Rhinolophus affinis) and systematically checked the expression pattern of bat-related virus receptors and chromatin accessibility across organs and cell types, providing a valuable dataset for studying the nature of infection among bat-borne viruses.

Drosophila has long been a successful model organism in multiple biomedical fields. Spatial gene expression patterns are critical for the understanding of complex pathways and interactions, whereas temporal gene expression changes are vital for studying highly dynamic physiological activities. Systematic studies in Drosophila are still impeded by the lack of spatiotemporal transcriptomic information.

The 0.8-Mb Ig new Ag receptor (IgNAR) region of the whitespotted bamboo shark () is incompletely assembled in Chr_44 of the reference genome. Here we used Cas9-assisted targeting of chromosome segments (CATCH) to enrich the 2 Mb region of the Chr_44 IgNAR loci and sequenced it by PacBio and next-generation sequencing.

In this work, we measured the millisecond residue specific protein folding and unfolding dynamics in cells for two protein GB3 mutants using NMR. The results show that the protein folding and unfolding dynamics in cells is different from that in buffer. Through a two-site exchange model, it is shown that both the population and the exchange rate are changed by the cellular environment.
