S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea
The FEBS Journal, EarlyView.S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

Post‐transcriptional regulatory networks: The dynamic interplay of RNA‐binding proteins
The FEBS Journal, EarlyView.Post‐transcriptional gene expression regulation is controlled by RNA‐binding proteins (RBPs), which influence many processes including splicing, localization, translation, and decay. Rather than acting alone, RBPs bind RNAs combinatorially, forming complex, context‐dependent regulatory networks.

Coordination of the Fe-S cluster biogenesis network by the sRNA RyhB in E. coli
RNA BiologyIron (Fe) plays critical roles as enzyme cofactor involved in key biological processes but can also lead to toxicity by catalysing the formation of highly damaging reactive oxygen species.

Expression of the entire polyhydroxybutyrate operon of Ralstonia eutropha in plants
Journal of Biological Engineering, 2017 Background Previously we demonstrated that an entire bacterial operon (the PRN operon) is expressible in plants when driven by the Tomato -yellow-leaf-curl-virus (TYLCV) -derived universal vector IL-60.

The FEBS Journal, EarlyView.Evolutionary and mechanistic divergence in the Hsp70–Hsp110 chaperone system. Prokaryotic Hsp70s probably diversified into multiple orthologues that cooperated with co‐chaperones such as JDPs and NEF, forming increasingly complex proteostasis networks.

The FEBS Journal, EarlyView.The genes PH0137, PH0138, and PH0140 form a cluster in the genome of Pyrococcus horikoshii. The PH0140 gene encodes a transcription factor identified as a d‐amino acid‐responsive regulatory protein (DARP). In feast mode, l‐Ile‐bound DARP binds to the promoter and represses transcription of PH0137 and PH0138. In famine mode, DARP binds to d‐allo‐Ile and

Journal of Animal Physiology and Animal Nutrition, EarlyView.ABSTRACT While β‐glucans from plants and yeasts have been extensively studied in weaned piglets, studies examining algae β‐glucans are scarce. Thus, the present study aimed to examine the effects of feeding algae β‐glucan in weaned piglets. Male, 21‐day‐old, weaned crossbred piglets were allotted to three experimental groups, which were fed either an ...

Journal of Phycology, EarlyView.Abstract The genus Merismopedia is morphologically characterized by its distinctive colony arrangement yet exhibits considerable variability among species. Recent studies suggested that Merismopedia is polyphyletic, and its most likely true lineage was provisionally placed within the Microcystaceae. However, the available molecular data for most of the
