Chloroplast intermembrane space
ID: chloroplast-intermembrane-space
The space between the two chloroplast envelope membranes.
It is topologically distinct from both the chloroplast stroma and the thylakoid lumen. Naming the compartments prevents a transport measurement across one barrier from being mistaken for transport across the entire chloroplast membrane system. [ref]
