油脂体的提取方法及其在食品中应用的研究进展Research progress on extraction methods and application in food of oleosomes

open access: yesZhongguo youzhi
旨在为油脂体的开发利用提供参考,综述了油脂体的结构与组成及提取方法,并介绍了油脂体在食品中的应用现状。油脂体以三酰甘油酯为核心,外层由磷脂-蛋白质膜覆盖,其主要由中性脂质、蛋白质和磷脂组成,此外还含有一些次要生物活性成分。油脂体的提取方法有水剂法、双螺杆压榨法和水酶法,可依据实际情况选择合适的提取方法。油脂体的特定结构以及生物活性成分使其作为天然预乳化水包油乳液具有良好的稳定性和乳化性能,在制备仿乳制品、可食用膜、乳液-凝胶以及作为脂肪替代品和生物活性物质运输载体等方面具有广阔的应用前景 ...

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...
