Automated backbone assignments were made using AutoAssign. Sidechain assignments were completed manually. Automated NOESY assignments were made using AutoStructure and structure solution was determined using AutoStructure and CYANA-2.1. The structure calculations were done including the C-terminal 6xHis tag LEHHHHHH. Resonance assignments were validated using AVS validation software. |
