Identification and Characterization of a Novel d-Branched-Chain Amino Acids Importer from Lactobacillus fermentum. [PDF]
ChembiochemCertain lactic acid bacteria produce d‐branched‐chain amino acids (d‐BCAA) and encode isoleucine 2‐epimerase (ILEP) and an uncharacterized transporter (AAP). We demonstrate that the transporter is a novel, non‐stereospecific BCAA importer. The ILEP‐AAP operon likely aids in storing and utilizing BCAA in a form less accessible to other organisms ...

Functional characterization of unique enzymes in Xanthomonas euvesicatoria related to degradation of arabinofurano-oligosaccharides on hydroxyproline-rich glycoproteins. [PDF]
PLoS ONE, 2018 In this study, we clarified the functions of three uncharacterized enzymes, XCV2724, XCV2728, and XCV2729, in Xanthomonas euvesicatoria, the causal agent of bacterial spot of tomato and pepper. The genes corresponding to the three enzymes are homologs of

Current Update on Intrinsic and Acquired Colistin Resistance Mechanisms in Bacteria
Frontiers in Medicine, 2021 Colistin regained global interest as a consequence of the rising prevalence of multidrug-resistant Gram-negative Enterobacteriaceae. In parallel, colistin-resistant bacteria emerged in response to the unregulated use of this antibiotic.
