Self‐Adjusting Engineered Probiotic for Targeted Tumor Colonization and Local Therapeutics Delivery

Advanced Science, EarlyView.
Zou et al. developed an engineered strain of Escherichia coli Nissle 1917 with precise targeting abilities for colonization and on‐demand payload release. The engineered probiotic survives and embolizes tumors only in the presence of more than 5 mM L‐lactate. Furthermore, the introduction of an α‐hemolysin circuit enhances its anti‐tumor effect.

Analysis of somatic mutations across the kinome reveals loss-of-function mutations in multiple cancer types

Scientific Reports, 2017
In this study we use somatic cancer mutations to identify important functional residues within sets of related genes. We focus on protein kinases, a superfamily of phosphotransferases that share homologous sequences and structural motifs and have many ...

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

METTL14‐Mediated M6A Modification of LINC01094 Induces Glucose Metabolic Reprogramming in Breast Cancer by Recruiting the PKM2/JMJD5 Complex

Advanced Science, EarlyView.
METTL14/IGF2BP2‐mediated m6A modification drives LINC01094 upregulation in BC. Then, LINC01094 interacts with PKM2 monomers to promote their dimerization, while serving as a flexible scaffold to facilitate the assembly of the PKM2/JMJD5 complex, synergistically stabilizing PKM2 dimers and enhancing their nuclear translocation.

Targeted Intervention Strategies for Maternal–Offspring Transmission of Christensenellaceae in Pigs via a Deep Learning Model

Advanced Science, EarlyView.
This study deciphers maternal‐driven microbial transmission in pigs using a deep learning model (maternal–offspring microbial transmission model), identifying Christensenellaceae R‐7 group as a key transmitted taxon. Filtered galacto‐oligosaccharides‐targeted Christensenellaceae R‐7 group alters offspring microbial functions via maternal ...

Phosphoenolpyruvate:carbohydrate phosphotransferase systems of bacteria

Microbiological Reviews, 1993
Numerous gram-negative and gram-positive bacteria take up carbohydrates through the phosphoenolpyruvate (PEP):carbohydrate phosphotransferase system (PTS). This system transports and phosphorylates carbohydrates at the expense of PEP and is the subject of this review.

Engineering Adenine Deaminase TadA for Precise and PAM‐Flexible Point Mutagenesis and Gradient‐Tuning Endogenous Protein Design

Advanced Science, EarlyView.
Base editing enables precise nucleotide substitutions but limited by bystander editing. This study engineers plant base editors by fusing optimized TadA variants with PAM‐flexible SpRY nickase, enabling A‐to‐G, C‐to‐T, and dual‐base conversions in a highly condensed window (≤3 nucleotides). Additionally, TadDBE (TadA Dual‐Base Editor)‐mediated directed

Phosphotransferases Associated with the Regulation of Kinesin Motor Activity*

Journal of Biological Chemistry, 1997
Kinesin, a plus-end-directed microtubule motor protein, functions in concert with accessory factors that have been shown to regulate enzyme activity and may also provide cargo specificity.

A Novel Class of Multi‐substituted Diaryl Scaffold Derivatives Inhibit Glioblastoma Progression by Targeting CD155

Advanced Science, EarlyView.
Structural modification of clofoctol yielded a novel blood‐brain barrier‐permeable compound, B7, featuring a multi‐substituted diaryl scaffold. B7 demonstrates potent anti‐glioblastoma activity by suppressing glioblastoma stem cells proliferation, migration, and invasion through interactions with five key residues of poliovirus receptor cell adhesion ...

The Phosphotransferase System in Solventogenic Clostridia

Microbial Physiology, 2015
The acetone-butanol-ethanol fermentation employing solventogenic clostridia was a major industrial process during the 20th century, but declined for economic reasons. In recent times, interest in the process has been revived due to the perceived potential of butanol as a superior biofuel.
