8IEX - PubMed Abstract:
The Arabidopsis WRKY11 (AtWRKY11) protein is an important transcription factor involved in plant response to biotic and abiotic stresses. Its DNA-binding domain specifically binds to gene promoter regions harboring the W-box consensus motif. Herein we report the high-resolution structure of the AtWRKY11 DNA-binding domain (DBD) determined by solution NMR spectroscopy. The results show that AtWRKY11-DBD adopts an all-β fold comprising five β-strands packed in an antiparallel topology, stabilized by a zinc-finger motif. Structural comparison reveals that the long β 1 -β 2 loop shows the highest structural variation from other available WRKY domain structures. Moreover, this loop was further found to contribute to the binding between AtWRKY11-DBD and W-box DNA. Our current study provides atomic-level structural basis for further understanding the structure-function relationship of plant WRKY proteins.
