Spore germination GerD central core domain
This is the central core domain found in GerD from a thermophilic Bacillus. GerD plays a critical role in nutrient receptor-mediated spore germination in Bacillus species. The crystal structure of GerD reveals this domain as a trimeric superhelical rope fold. Alterations in GerD structure have profound effects on spores' nutrient germination.
