pleated sheet 中文意思是什麼
pleated sheet
解釋
片層-
Ag + and fe2 + caused the fluorescence of trp residues in g6pd quenched ; mg2 + and edta made fluorescence intensity of g6pd increased, this indicates that they caused trp residues wrapped and came to the inner core and located in the hydrophobic area ; while zn2 + or mn2 + made fluorescence intensity of g6pd decreased, this indicates that they made the conformation of g6pd relaxed and chromophores exposed to polarity environments. in native condition and in the far circular dichroic ( cd ) region, g6pd exhibited two characteristic negative band centered at 208nm and 222nm respectively, thus it is estimated to contain about 41. 2 % a - helix, 20. 6 % - pleated sheet and 38. 2 % random coil and turn
Ag ~ +和fe ~ （ 2 + ）引起色氨酸（ trp ）殘基的熒光淬滅； mg ~ （ 2 + ）和edta均使g6pd的熒光強度增強，說明它們使trp殘基重新包裹在分子內部而處于疏水的微環境中； zn ~ （ 2 + ）和mn ~ （ 2 + ）均使g6pd的熒光強度變小，說明它們使酶分子構象變得疏鬆，原來處在分子內部的發色團暴露在極性環境中。
