Understanding the protein complexes involved in the reception of the plant hormone Strigolactone
… receptor also functions as a slow enzyme that hydrolyses SL into two non-active by-products. The hydrolytic function of the receptor is essential for SL signalling and enables the receptor to interact with the downstream signalling proteins, such as the Skp-Cullin-F-box (SCF) E3 ligase complex …
