The structural biology of type IV secretion systems [PDF]
Nature Reviews Microbiology, 2009 Type IV secretion systems (T4SSs) are versatile secretion systems that are found in both Gram-negative and Gram-positive bacteria and secrete a wide range of substrates, from single proteins to protein-protein and protein-DNA complexes. They usually consist of 12 components that are organized into ATP-powered, double-membrane-spanning complexes.

Structure and Biology of Type VIII Collagen.
Trends in Glycoscience and Glycotechnology, 1992 VIII型コラーゲンは、ウシ大動脈内皮細胞の培養系における生合成産物として最初に報告されたので、従来は内皮細胞コラーゲン (EC) と呼ばれていた。このタンパク質は現在、トリおよび哺乳類のケラチノサイト、線維芽細胞、星状細胞腫や他の腫瘍細胞、さらに様々な大きさの血管に由来する内皮細胞などによって分泌されることが知られている。生体内ではVIII型コラーゲンの分布は限られており、例えば髄膜、骨膜、軟骨膜、角膜のデスメ膜などの細胞外マトリックスに存在する。また大小血管の内皮下層や内皮細胞の発芽培養系で形成される毛細血管様構造にも存在する。タンパク質のアミノ酸配列と核酸塩基配列から、VIII型コラーゲンはα1 (VIII) およびα2 (VIII ...
