Functionalization of bacterial microcompartment shell interior with cysteine containing peptides enhances the iron and cobalt loading capacity

In this study, we present a method for functionalizing recombinant GRM2-type BMC shell lumens with short cysteine-containing sequences and demonstrate that the iron and cobalt loading capacity of such modified shells is markedly increased. These results also imply that a passive flow of cobalt and iron atoms across the BMC shell could be possible.PMID:37728832 | DOI:10.1007/s10534-023-00538-1
