Figure 7: A model of SL recognition and SL hydrolysation and the regulation of SL-induced signal transduction by D14.
From: Molecular mechanism of strigolactone perception by DWARF14
(a) The empty form of D14. (b) SL-bound D14. (c) SL is catabolized by D14, and D-OH is produced. D-OH then remains at the aperture area of the binding cavity of D14. (d) The hydrophobic surface of the cap structure of D14 is recognized by a target protein, such as SLR1, and the D14-SL-target protein complex modulates downstream signalling. (+)-5-deoxystrigol was shown in this model as a representative of natural SLs.
