Structural and functional analysis of Bacillus sarcosine oxidase and its activity toward cyclic imino acids

open access: yesFEBS Open Bio, EarlyView.
Sarcosine oxidase from Bacillus sp. (SoxB) recognizes l‐proline (l‐Pro), d‐proline (d‐Pro), and l‐thioproline (l‐Tpr) as minor substrates. In this study, we measured their absorption spectra, determined the crystal structures of their enzyme complexes, and performed site‐directed mutagenesis of key residues.

Interplay between RNA‐protein interactions and RNA structures in gene regulation

open access: yesFEBS Open Bio, EarlyView.
Methodological advances in mapping transcriptome‐wide RNA‐protein interactions and RNA structures have started to uncover the potential of RNP conformations in gene regulation. Competing RNA–RNA, RNA‐protein and protein–protein interactions shape the compaction and function of RNPs throughout their lifetime and may provide novel therapeutic targets in ...

Research progress on the metabolic transformation of Shenling Baizhu San under the influence of the gut microbiota

open access: yesAdvanced Chinese Medicine, EarlyView.
Abstract The gut microbiota plays a pivotal role in maintaining host metabolic homeostasis and overall physiological functions. Shenling Baizhu San (SLBZS), a time‐honored classical prescription for tonifying Qi, strengthening the spleen, removing dampness, and arresting diarrhea, has shown broad clinical efficacy in digestive disorders.
