Expression in E.coli generates nanocompartments with an average diameter of 25 nm. They can be disassembled by treatment with 6M guanidine hydrochloride and reassembled with cargo. The nanocompartment is probably involved in sulfur metabolism (PubMed:33821786). Probably allows passage of cysteine into its interior; during growth in light the physiological pH is 8-8.4, about 30-54% of free cysteine (charge -1) would be able to pass through the shell (Probable).
