X-ray crystal structure of the Pyr1-pyrabactin A complex

Template:ABSTRACT PUBMED 20729860

Function

[PYR1_ARATH] Receptor for abscisic acid (ABA) required for ABA-mediated responses such as stomatal closure and germination inhibition. Inhibits the activity of group-A protein phosphatases type 2C (PP2Cs) when activated by ABA.^{[1] [2] [3]}

About this Structure
