Biochemical properties of FRET-based ABA reporters
ABA reporter | ABA receptor |
K’d [µM] |
In vitro DR |
---|---|---|---|
ABACUS1-2 µ | PYL1 H87P | 2 | 1.6 |
ABACUS1-80 µ | PYL1 | 80 | 2.6 |
ABAleon2.1 | PYR1 | 0.1 | 1.1 |
ABAleon2.15 | PYR1 H115A | 0.5 | 1.1 |
Indicated are the reporter names, the ABA receptor incorporated in the sensory module, their apparent ABA affinity (K’d) and in vitro dynamic range (DR) calculated from ABA-bound emission ratio/ ABA-unbound emission ratio.
