AMINOGLYCOSIDE RESISTANCE GENES IN Pseudomonas aeruginosa ISOLATES FROM CUMANA, VENEZUELA

Revista do Instituto de Medicina Tropical de São Paulo, 2016
The enzymatic modification of aminoglycosides by aminoglycoside-acetyltransferases (AAC), aminoglycoside-adenyltransferases (AAD), and aminoglycoside-phosphotransferases (APH), is the most common resistance mechanism in P.

The ketogenic diet alters microbiome‐metabolome profiles to improve West syndrome therapy

Pediatric Investigation, EarlyView.
The ketogenic diet alleviates West syndrome by reshaping gut microbiota (increasing Bacteroides, Parabacteroides, and reducing Escherichia and Bifidobacterium), and modulating metabolites—including anticonvulsant lipids (e.g., capric acid), suppressed harmful lipids (e.g., 2‐methylbutyroylcarnitine), and amino acids and analogs (e.g., 3‐sulfinoalanine)—

Genetic engineering for SIT application: a fruit fly‐focused review

Insect Science, EarlyView.
Abstract Sterile insect technique (SIT) has become a key component of efficient pest control. Fruit fly pests from the Drosophilidae and Tephritidae families pose a substantial and overwhelmingly increasing threat to the agricultural industry, aggravated by climate change and globalization among other contributors.

Amikacin: Uses, Resistance, and Prospects for Inhibition

Molecules, 2017
Aminoglycosides are a group of antibiotics used since the 1940s to primarily treat a broad spectrum of bacterial infections. The primary resistance mechanism against these antibiotics is enzymatic modification by aminoglycoside-modifying enzymes that are

The return of metabolism: biochemistry and physiology of glycolysis

Biological Reviews, EarlyView.
ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...

Structural analysis of the NifL‐NifA complex reveals the molecular basis of anti‐activation of nitrogen fixation gene expression in Azotobacter vinelandii

The FEBS Journal, EarlyView.
Using cryo‐EM combined with biochemical and genetic approaches, we mapped the interaction surface between NifL and NifA to gain insights into the regulation of nitrogen fixation genes in A. vinelandii. Our findings suggest that NifL, a homolog of histidine kinases lacking phosphorylation activity, evolved to act as a steric block of NifA activity ...

Enzymic synthesis of ether types of choline and ethanolamine phosphoglycerides by microsomal fractions from rat brain and liver

Journal of Lipid Research, 1977
The formation of product by ethanolamine phosphotransferases (EC 2.7.8.1) and cholinephosphotransferases (EC 2.7.8.2) in microsomal fractions from brains and livers of mature rats is increased several fold by 1,2-diacyl-sn-glycerols. With the addition of

Chromogenic Detection of Aminoglycoside Phosphotransferases [PDF]

Antimicrobial Agents and Chemotherapy, 1998
ABSTRACT A coupled chromogenic reaction (based on an agar overlay combining NADH, pyruvate kinase, lactate dehydrogenase, phosphoenolpyruvate, ATP, and kanamycin sulfate with thiazolyl blue-phenazine methosulfate for detection of NADH consumption) was optimized for the detection of aminoglycoside phosphotransferases (APHs).

A short peptide derived from late embryogenesis abundant proteins enhances acid tolerance in Escherichia coli via modulation of two‐component regulatory systems

The FEBS Journal, EarlyView.
Expression of the LEA‐K peptide in E. coli BL21 (DE3) improved bacterial viability under acidic stress (pH4), suggesting a protective function. RNA‐sequencing of LEA‐K‐expressing vs. non‐expressing cells revealed 283 differentially expressed genes (DEGs). In silico docking linked LEA‐K to two‐component systems (TCS) proteins (Rcs, BtsS/R, and EnvZ/OmpR)

Unlocking nitrogen regulation: structural insights into the NifL‐NifA complex and prospects for engineered diazotrophs

The FEBS Journal, EarlyView.
The urgent need for sustainable agriculture places biological nitrogen fixation at the forefront of current biotechnological research. Plant growth‐promoting rhizobacteria play crucial roles in agriculture by enhancing nutrient absorption, regulating hormonal balance, and providing reduced nitrogen to plants. Among these, diazotrophic bacteria, such as
