Hsp70 diversification and repurposing across the tree of life: Lessons from the evolutionary and mechanistic trajectory of the Hsp70–Hsp110 chaperone system

open access: yesThe 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.

Predicting The Operon Structure Of Bacillus Subtilis Using Operon Length, Intergeene Distance, and Gene Expression Information

open access: yes, 2004
Introduction In prokaryotes, open reading frames (ORFs) belonging to the same operon are transcribed together into a single mRNA molecule. To understand gene regulation in prokaryotic organisms, as a first step it is important to determine the operon ...

A distinct gene expression mechanism for d‐amino acid utilization in hyperthermophilic archaeon Pyrococcus horikoshii

open access: yesThe 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

Characterization of the Bacillus subtilis pur operon

open access: yes, 1988
The Bacillus subtilis pur operon was characterized to better understand genetic organization and regulation in this gram positive bacterium. Over 13 kilobase pairs of DNA containing the pur operon were cloned and sequenced.

Oral and Pancreatobiliary Microbiota in Cancer: A Systematic Review of Compositional Alterations and Their Clinical Implications

open access: yesJournal of Oral Pathology &Medicine, EarlyView.
ABSTRACT Background Associations between microbial dysbiosis and malignancies of the pancreatobiliary system have been described in recent studies. As a result of the limited number of studies that have been done specifically on the malignancies of the biliary tract, information regarding oral, biliary and tumour‐related microbial alterations was ...

FucR Functions as a Transcriptional Regulator for L-Fucose Utilization in Campylobacter jejuni

open access: yesMicroorganisms
Campylobacter jejuni is an enteric pathogen and a major cause of foodborne illness worldwide. It has been shown that C. jejuni primarily utilizes amino acids as its preferred energy source, but its ability to utilize L-fucose can grant a competitive ...

Comprehensive revision of Mallomonas sect. Peroneides stat. nov. (Chrysophyceae) integrating morphology and multigene phylogeny

open access: yesJournal of Phycology, EarlyView.
Abstract Mallomonas is among the most diverse genera of Chrysophyceae, yet many of its lineages remain taxonomically unresolved due to limited molecular sampling. Mallomonas series Peronoides, historically limited to four species, has posed persistent taxonomic difficulties, most notably the long‐standing and problematic reliance on a rare ...

rRNA operon improves species-level classification of bacteria and microbial community analysis compared to 16S rRNA

open access: yesMicrobiology Spectrum
Precise identification of species is fundamental in microbial genomics and is crucial for understanding the microbial communities. While the 16S rRNA gene, particularly its V3-V4 regions, has been extensively employed for microbial identification ...
