Icosahedral inclusions (carboxysomes) of Nitrobacter agilis.

摘要: The icosahedral bodies of Nitrobacter agilis are about 120 nm in diameter and, as viewed by electron microscopy, consist an outer shell enclosing 10-nm particles. inner particle is the enzyme D-ribulose 1,5-bisphosphate carboxylase. isolated from cells incubated 1 month without nitrite had a specific activity for 0.54 mu mol CO2 fixed per min mg protein.
