“…Zhang et al . (2022b) confirmed that the addition of zinc can promote the growth of LAB and increase their hydrogen production. Compared with zinc sulphate, a commonly used zinc supplement, SPZnC have antioxidant properties and low toxicity (Jiang et al ., 2014; Duan et al ., 2021), which makes them more suitable as a zinc source for the growth of LAB.…”

SummaryThis study was conducted to investigate the effects of the addition of different hydrophobic peptides and their zinc complexes on the growth and fermentation of lactic acid bacteria (LAB). According to the results of peptide surface hydrophobicity assays, three distinct hydrophobic peptides were isolated from soybean peptides (SP). The UV and FTIR measurements revealed that the peptide‐zinc complexes (SPZnC) were successfully prepared. The LAB group supplemented with ZnSPC exhibited significantly higher biomass, viable bacteria count, acid production capacity, and glucose consumption compared to the LAB group supplemented with other components such as organic zinc, inorganic zinc, and peptide. Among these supplements, Zn‐MHP demonstrated the most pronounced promotion of Lactobacillus growth and fermentation. Furthermore, additional fermentation experiments conducted on curdled fermented milk demonstrated that the inclusion of Zn‐MHP resulted in improved quality and reduced fermentation time. These findings suggest that Zn‐MHP possesses the ability to enhance the physiological function of LAB.

“…It has been proposed that this two-component system participates in cellular Zn 2+ balance as well as Zn 2+ overload protection via metal ion sequestration via ZraP . In addition to sensing Zn 2+ , experiments have also found that ZraSR regulates hydrogenase 3 formation, a portion of the formate hydrogen lyase complex that is involved in fermentative H 2 production, which is a significant product in microbial metabolism . This intriguing duality of the ZraSR system remains to be explored further.…”

Bacteria survive in highly dynamic and complex environments due, in part, to the presence of systems that allow the rapid control of gene expression in the presence of changing environmental stimuli. The crosstalk between intra-and extracellular bacterial environments is often facilitated by two-component signal transduction systems that are typically composed of a transmembrane histidine kinase and a cytosolic response regulator. Sensor histidine kinases and response regulators work in tandem with their modular domains containing highly conserved structural features to control a diverse array of genes that respond to changing environments. Bacterial two-component systems are widespread and play crucial roles in many important processes, such as motility, virulence, chemotaxis, and even transition metal homeostasis. Transition metals are essential for normal prokaryotic physiological processes, and the presence of these metal ions may also influence pathogenic virulence if their levels are appropriately controlled. To do so, bacteria use transition-metal-sensing two-component systems that bind and respond to rapid fluctuations in extracytosolic concentrations of transition metals. This perspective summarizes the structural and metal-binding features of bacterial transition-metal-sensing two-component systems and places a special emphasis on understanding how these systems are used by pathogens to establish infection in host cells and how these systems may be targeted for future therapeutic developments.
