Pisum sativum (Garden pea) Strigolactone esterase, PsD14, RAMOSUS 3, RMS3

Comment

Involved in strigolactone signaling pathway. Functions downstream of strigolactone synthesis, as a component of hormone signaling and as an enzyme that participates in the conversion of strigolactones to the bioactive form. Binds and hydrolyzes the synthetic strigolactone analog GR24 and its enantiomers in vitro. Forms a stable covalent complex with the D-ring of strigolactone, which is essential for hormone bioactivity. The D-ring is attached to His-247 of the catalytic triad. The hydrolysis of strigolactone into a covalently linked intermediate molecule is required to trigger strigolactone signaling. This mechanism defines RMS3 as a non-canonical hormone receptor with dual functions to generate and sense the active form of strigolactone
