It is demonstrated that MxtR/ErdR directly regulates the methylcitrate cycle and coordinates both acetate and propionate metabolism, identifying this signaling system as a central regulator of SCFA homeostasis in P. alloputida KT2440.
Analysis of strain-specific transcriptomic and metabolic responses of Clostridium butyricum and Bacteroides thetaiotaomicron grown in pure anaerobic culture with 0.1% MSG suggested that MSG's physiological effects may depend on which bacterial groups dominate an individual’s microbiome.
Exogenous C16:1 elicited a focused transcriptional adjustment rather than broad transcriptome-wide reprogramming in salt-stressed Z. rouxii, indicating that peroxisome-linked lipid processes and redox regulation were candidate mechanisms underlying fatty-acid-associated halotolerance and provided targets for improving...

These findings provide a promising strategy for engineering NMN-producing food-grade microbial cell factories by overcoming a paradoxical downregulation of the pentose phosphate pathway (PPP) in a GntR-family transcription factor.

ABSTRACT Mycobacterium tuberculosis (Mtb) survives host defenses by adapting to host conditions, including acid stress, during infection. A critical survival strategy involves pH homeostasis, mediated by complex signaling systems that regulate metabolic reprogramming and stress responses. While the lysine acetyltransfe...

This work establishes a generalizable framework for multi-compartment malonyl-CoA utilization in eukaryotic cell factories through dynamic control of HFA1 and optimized POS5 expression, and develops a dual-compartment coordination strategy to efficiently exploit cytosolic and mitochondrial malonyl-CoA pools.
