Recent advances in recombinase polymerase amplification: Principle, advantages, disadvantages and applications

Frontiers in Cellular and Infection Microbiology, 2022
After the outbreak of SARS-CoV-2, nucleic acid testing quickly entered people’s lives. In addition to the polymerase chain reaction (PCR) which was commonly used in nucleic acid testing, isothermal amplification methods were also important nucleic acid ...

Safety evaluation of the food enzyme asparaginase from the genetically modified Aspergillus oryzae strain NZYM‐OA

EFSA Journal, 2023
The food enzyme asparaginase (l‐asparagine amidohydrolase; EC 3.5.1.1) is produced with the genetically modified microorganism Aspergillus oryzae strain NZYM‐OA by Novozymes A/S. The genetic modifications do not give rise to safety concerns.

Post market environmental monitoring of genetically modified herbicide tolerant crops (Working group report from the 4th international workshop on PMEM of genetically modified plants, Quedlinburg, Germany 2010) [PDF]

, 2011
According to European Union (EU) legislation, genetically modified (GM) crops released for commercial cultivation have to be monitored. Here we summarise the discussion of a working group that convened during the 4th International Workshop on Post Market

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Safety management status for genetically modified microorganism and related products used for food industry

Zhongguo shipin weisheng zazhi
Genetically modified microorganism （GMM）， also known as recombinant DNA microorganism， means a micro-organism in which the genetic material has been altered in a way that does not occur naturally by mating and/or natural recombination.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Safety of l‐lysine sulfate produced by fermentation with Escherichia coli CGMCC 3705 for all animal species

EFSA Journal, 2017
In 2015, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) issued an opinion on the safety and efficacy of l‐lysine sulfate produced by fermentation with Escherichia coli CGMCC 3705, when used as a nutritional additive ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Genetically Programmed Shape‐Morphing of Engineered Living Materials

Advanced Functional Materials, EarlyView.
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with
