However, due to insufficient EM density to observe the amino acid side chains, it is unclear which specific segment of alpha-synuclein is visualized in the structure. Therefore, we opted to modeled it as poly-UNK. 由来: (組換発現) Homo sapiens (ヒト) / 発現宿主: ![]() #2: タンパク質 | 分子量: 10820.836 Da / 分子数: 12 / 由来タイプ: 組換発現 / 由来: (組換発現) Homo sapiens (ヒト) / 遺伝子: SNCA, NACP, PARK1 / 発現宿主: ![]() #3: 化合物 | ChemComp-A1EFL / ( 分子量: 436.502 Da / 分子数: 12 / 由来タイプ: 合成 / 式: C23H21FN4O2S / タイプ: SUBJECT OF INVESTIGATION #4: 水 | ChemComp-HOH / | 研究の焦点であるリガンドがあるか | Y | Has protein modification | N | |
