  1. States are assigned to the experiments during which they occurred. The state vectors of experiments 1 to 8 are shown in Table 3. Difference vectors and additional decomposed reactions that appeared in more than one experiment are listed only once. States of Pst, PhoU, PhoR, and PhoB were considered as P-invariants. Phosphate, PhoR, PhoRP and the cytoplasmic PhoA protein were excluded as catalytic factors based on biological knowledge.
