a在β折叠中,两条以上氨基酸链(肽链),或同一条肽链之间的不同部分形成平行或反平行排列,成为“股”。肽平面之间呈手风琴状折叠,股与股之间会通过氢键固定,但氢键主要在股间而不是股内。氨基酸残基的R侧链分布在片层的上下。 In beta the fold, two above amino acid chains (peptide chain), either between ...
免疫球蛋白有大量的β折叠层。 Can form beta the folding amino acid remnant base not to be generally big, moreover does not accompany plants the electric charge, like this is advantageous to the multi-peptide chain extension, like the glycine, the alanin the probability which appears in beta ...
