It is not uncommon for protein-protein interactions in the transmembrane signaling to exhibit low binding affinities with a dissociation constant in the μM range or higher. Presumably, membrane proteins can selectively bind with their binding partners via low-affinity interactions because they can only diffuse laterally in the membrane plane and interact with the partners within a limited space on the membrane surface or within the membrane. This review focuses on the crystallographic studies on cell-surface receptors and intramembrane proteases that perform the transmembrane signaling mediated by low-affinity protein-protein interactions.","PeriodicalId":74311,"journal":{"name":"Nihon Kessho Gakkai shi","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88804673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

BCZTにおいて,Aサイトを占有するCa2+イオンの半 径(1.34 Å)は,置換元のBa2+イオンの半径(1.61 Å)より も約17%も小さいため,Ca2+イオン周囲の局所構造は母 材のBaTiO3の構造とは大きく異なっていると考えられ る.そこで,著者らは元素選択的に三次元局所構造を導 出可能なXFHを,Caのみをドープした(Ba0.9Ca0.1)TiO3 に適用し,同じAサイトを占めるCaおよびBaまわりの 局所構造を区別して解析することで,両者に大きな違い があることを見出した.7)本稿では,その結果について紹 介する. 図1a,bに,大型放射光施設SPring-8のBL13XUにお いて実施したXFH測定によって得られたCaおよびBaま わりの原子像を示す.ここでは,図1cに示すように中心 元素であるCaもしくはBaを含む<001>面を再生して いる.図1a,bにある〇は,BaTiO3の結晶構造から予測 されるAサイトカチオンの理想位置に対応している.Ba まわりの原子像は,〇の位置の中央に観測されるのに対 し,Caまわりでは原子像が中央に向かって変位している ことがわかる.このことは,Caまわりで格子が局所的に 収縮していることを示している.これは,Caイオンの半 径がBaイオンよりも小さいことと符合している. 図2a,bには,図1a,bにおいて矢印で示した原子像を 拡大して表示している.CaおよびBaまわりにおいて,原 子像の位置だけではなく形状にも大きな違いがあること","PeriodicalId":74311,"journal":{"name":"Nihon Kessho Gakkai shi","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73646102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
