Heterodimeric interactions among the 1-amino-cyclopropane-1-carboxylate synthase polypeptides encoded by the Arabidopsis gene family






Fig. 8. Detection of protein–protein interaction during intermolecular complementation of ACSs by bimolecular fluorescence complementation. (I) Detection of heterodimerization between K278A and Y92A mutants of ACS4 and ACS7 that yields active or inactive heterodimers depending on which polypeptide provides the wt K278. (II) Detection of heterodimerization between ACS1 and the K278A and Y92A mutants of ACS6 that yields active or inactive heterodimers, depending on which polypeptide provides the wt K278. I A–C and II A–C are the same as in Fig. 5 B-D and F-H, except that they correspond to ACS4/ACS7 and ACS1/ACS6 heterodimers, respectively.
