Abstract
(EN) Disclosed are: a novel Escherichia coli membrane protein insertion factor which is involved in the intake of a protein; and a method for utilizing the Escherichia coli membrane protein insertion factor particularly in the synthesis of a membrane protein in a cell-free system and the insertion of a protein into a membrane which occurs in conjunction with the aforementioned synthesis. Specifically disclosed is a membrane protein insertion factor in a highly purified form, which is characterized by having a structure represented by chemical formula (Ia) or (II). (In the formulae, R1 represents a saturated /unsaturated fatty acid residue that has a carbon chain containing 16 to 20 carbon atoms; R2 represents a hydrogen atom or an acetyl group; n represents an integer of 20 or less; GlcNAc represents N-acetylglucosamine; ManNAcA represents N-acetylmannosamine uronic acid; and Fuc4NAc represents 4-N-acetylaminofucose.)
(FR) La présente invention concerne : un nouveau facteur d'insertion de protéines membranaires d'Escherichia coli qui est impliqué dans l'absorption d'une protéine; et un procédé destiné à utiliser le facteur d'insertion de protéines membranaires d'Escherichia coli en particulier dans la synthèse d'une protéine membranaire dans un système exempt de cellules et l'insertion d'une protéine à l'intérieur d'une membrane qui a lieu en association avec la synthèse mentionnée précédemment. L'invention concerne spécifiquement un facteur d'insertion de protéines membranaires sous une forme hautement purifiée, qui est caractérisé en ce qu'il a une structure représentée par les formules chimiques (Ia) ou (II). (Dans les formules, R1 représente un résidu acide gras saturé/insaturé ayant une chaîne carbonée contenant de 16 à 20 atomes de carbone; R2 représente un atome d'hydrogène ou un groupe acétyle; n représente un entier inférieur ou égal à 20; GlcNAc représente une N-acétylglucosamine; ManNAcA représente un acide N-acétylmannosamine-uronique; et Fuc4NAc représente le 4-N-acétylaminofucose.)
