**31. Soybean disease resistance protein RHG1-LRR domain**

RHG1 encoded by rhg1 was a soybean transmembrane receptor-like kinase (EC 2.7.11.1) with an extracellular leucine-rich repeat (LRR) domain. The LRR of RHG1 was believed to be in‐ volved in elicitor recognition and interaction with other plant proteins. Afzal and Lightfoot ex‐ pressed the LRR domain in Escherichia coli (RHG1-LRR) and produce refolded protein [34].
