Chlamydomonas reinhardtii

association between binding protein CP12 and phosphoribulokinase (EC 2.7.1.19), glyceraldehyde 3-phosphate dehydrogenase (EC 1.2.1.13) and aldolase. The dissociation constant between CP12 and fructose 1,6-bisphosphate (EC 4.1.2.13) aldolase is 0.00048 mM and thus corroborates an interaction between CP12 and aldolase. The dissociation constant between aldolase and the phosphoribulokinase/lyceraldehyde 3-phosphate dehydrogenase/CP12 complex is 55 mM
