Comments The shell of the carboxysome presents a formidable barrier to the passage of thioredoxin and glutaredoxin proteins as the pores that perforate it [generally ~6 Å in diameter, though recent work suggests that gated pores as large as 14 Å may also be present (BNID 106096)] allow passage of small metabolites, but not proteins.
