Table 3.

Two letter prefixes that identify the sub-cellular localization of metabolites

Prefix Cellular Compartment
CY Cytosol
CS Chloroplast stroma
GL Golgi lumen
ER ER
VC Vacuole
NC Nucleus
MT Mitochondrion

This lexicon of prefixes can be easily extended to include other cellular compartments. For example, we would use the three-letter prefix ERL to pinpoint localization to the ER lumen.
