“…Oscillations play important roles in many dynamic cellular processes in both eukaryotes and prokaryotes 54 . For example, Min proteins oscillate in bacteria from one pole to the other, helping the bacteria to divide at appropriate time and place 54–56 . In addition, Tanouchi et al .…”

Silver (Ag) in various forms have recently gained broad interest and been revisited due to their promising antimicrobial effects. Here we report our study on the morphological dynamics of live bacteria when subjected to Ag + ions. Using time-lapse microscopy, we observed oscillations of cell-length for a large fraction of bacteria exposed to 60 μ M of Ag + ions. In addition, we found that the responses of bacteria to Ag + ions were heterogeneous. We quantified the oscillations of cell-length with power spectral density, which appeared different from that of bacteria growing in the absence of Ag + ions. Furthermore, a model similar to the predator-prey argument was developed to understand the observed oscillations of cell-length upon exposure to Ag + ions. This model not only successfully produced the oscillations but also explained the observed heterogeneity in the bacterial responses to Ag + ions.

“…2 and S1 ). It is known that neither MinD nor MinE alone can restore the requirement of the Min system in cell division, and a similar trend was observed in flagellar regulation ( 26 , 27 ). Further, the number of bacteria containing flagella was determined and plotted ( Fig.…”

Background: Protein oscillations have been one of the major highlights in the field of biophysics and bio-molecules. These oscillations can give us insights into complex bio-molecules and reveal their nature at a very fundamental level. They can also show us the dynamics involved in the functioning of bio-molecules through the nature of these oscillations. Method/Objective: In this article, we have described the basics of protein oscillations, giving a very fundamental approach to the physics of oscillations. We have also described some bio-systems in which protein oscillations play a vital role. In this article, we have used the Langevin equations and Fokker-Planck equations to describe the oscillation dynamics of proteins. Findings:Finally, we have shown the trend of an increase in the entropy of the oscillations by involving a perturbation term in the regular nature of oscillations. The entropy of protein oscillations is very important in understanding protein dynamics. Doi: 10.28991/HEF-SP2022-01-05 Full Text: PDF
