Toxic effect and inability of L-homoserine to be a nitrogen source for growth of Escherichia coli resolved by a combination of in vivo evolution engineering and omics analyses

Frontiers in Microbiology, 2022
L-homoserine is a pivotal intermediate in the carbon and nitrogen metabolism of E. coli. However, this non-canonical amino acid cannot be used as a nitrogen source for growth.

Homoserine Esterification in Green Plants [PDF]

Plant Physiology, 1974
EXTRACTS OF PHYLOGENETICALLY DIVERSE PLANS WERE SURVEYED FOR THEIR ABILITY TO SYNTHESIZE THE FOLLOWING HOMOSERINE ESTERS WHICH ARE POTENTIAL PRECURSORS FOR METHIONINE AND THREONINE SYNTHESIS IN GREEN PLANTS: O-acetyl-, O-oxalyl-, O-succinyl-, O-malonyl-, and O-phosphohomoserine. Synthesis of O-acylhomoserine esters was detected only in Pisum sativum L.

Promoter selectivity of the RhlR quorum-sensing transcription factor receptor in Pseudomonas aeruginosa is coordinated by distinct and overlapping dependencies on C4-homoserine lactone and PqsE.

PLoS Genetics, 2023
Quorum sensing is a mechanism of bacterial cell-cell communication that relies on the production and detection of small molecule autoinducers, which facilitate the synchronous expression of genes involved in group behaviors, such as virulence factor ...

Identification of Quorum-Sensing Molecules of N-Acyl-Homoserine Lactone in Gluconacetobacter Strains by Liquid Chromatography-Tandem Mass Spectrometry

Molecules, 2019
Many Gram-negative bacteria can regulate gene expression in a cell density-dependent manner via quorum-sensing systems using N-acyl-homoserine lactones (AHLs), which are typical quorum-sensing signaling molecules, and thus modulate physiological ...
