Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

The efficacy of immediate versus delayed antibiotic administration on bacterial growth and biofilm production of selected strains of uropathogenic Escherichia coli and Pseudomonas aeruginosa

open access: yesInternational Brazilian Journal of Urology, 2015
Purpose The treatment of urinary tract infections (UTI) with antibiotics is commonly used, but recurrence and antibiotic resistance have been growing and concerning clinicians. We studied whether the rapid onset of a protective biofilm may be responsible

Biophysical investigation of bacterial aggregation [PDF]

open access: yes, 2008
In nature, bacteria usually exist as aggregates, in order to withstand changes in environmental conditions. Bacterial aggregation is of great significance in the field of biotechnology, environmental studies and medicine.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Experimental evolution for the recovery of growth loss due to genome reduction

open access: yeseLife
As the genome encodes the information crucial for cell growth, a sizeable genomic deficiency often causes a significant decrease in growth fitness. Whether and how the decreased growth fitness caused by genome reduction could be compensated by evolution ...

THE EFFECT OF AEROB AND ANAEROBIC CONDITION AND ADDITION OF CaCO3 ON THE GROWTH AND ANTIBACTERIAL ACTIVITY OF LACTIC ACID BACTERIA ISOLATED FROM LAYER HENS INTESTINE AFTER ADMINISTRATED OF AKBISprob

open access: yesJurnal Kedokteran Hewan, 2023
This study aimed to determine the effect of aerobic and anaerobic incubation, and the addition of CaCO₃ on the growth and antibacterial activity of Lactic Acid Bacteria (LAB) isolated from laying hens’ intestines (strain ISA Brown) after given 4 ...

Duboisia leichhardtii (f.Muell.) extracts inhibit the growth of bacterial triggers of selected autoimmune inflammatory diseases

open access: yes, 2016
Introduction: Duboisia leichhardtii F.Muell. is a medium to large tree which is native to subtropical regions of eastern Australia. Duboisia spp. contain a number of psychoactive tropane and pyrrolidine alkaloids with reported antibacterial activity ...

Antimicrobial surfaces based on self-assembled nanoreactors : from block copolymer synthesis to bacterial adhesion study [PDF]

open access: yes, 2010
The aim of this work is to develop a new strategy for the prevention of biofilm growth. For this purpose, we prepared bioactive surfaces resulting from the surface-immobilization of nanoreactors self-assembled from amphiphilic poly(isobutylene)-block ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
