The different types of protein-reaction-location relationships. There are four types of protein-reaction-location relationships: (a) one reaction is related to one protein; (b) one reaction is related to two or more proteins which are all in the same locations; (c) one reaction is related to two or more proteins which are in completely different locations; (d) one reaction is related to two or more proteins which have common locations, but some of them also have their unique location annotation. SCLsc stands for the common locations. The number of reactions in each type is shown in the parentheses.
