The ins and outs of metal homeostasis by the root nodule actinobacterium Frankia [PDF]
, 2014 Background: Frankia are actinobacteria that form a symbiotic nitrogen-fixing association with actinorhizal plants, and play a significant role in actinorhizal plant colonization of metal contaminated areas.

Bioinformatic Mapping of Opine-Like Zincophore Biosynthesis in Bacteria
mSystems, 2020 Zinc is an essential nutrient in biological systems due to its structural or catalytic requirement in proteins involved in diverse cellular processes. To meet this cellular demand, microbes must acquire sufficient zinc from their environment.

X-ray microtomographic visualization of Escherichia coli by metalloprotein overexpression [PDF]
J.Synchrotron Radiat. 20 (2013) 581-586, 2016 This paper reports X-ray microtomographic visualization of the microorganism Escherichia coli overexpressing a metalloprotein ferritin. The three-dimensional distribution of linear absorption coefficients determined using a synchrotron radiation microtomograph with a simple projection geometry revealed that the X-ray absorption was homogeneously ...
