Abstract

Charge transfer has been observed between oxidised tryptophan-26 units and the tyrosine-21 or -24 of the coat protein of fd phage. The transfer is likely to be intramolecular. The rates suggest that the aromatic units are in a rigid region and that they may have at least two different environments. No apparent interaction occurs with the DNA, consistent with tryptophan and tyrosine units not being in contact with the bases.

摘要

已观察到氧化的色氨酸-26单元与fd噬菌体外壳蛋白的酪氨酸-21或-24之间存在电荷转移。这种转移可能是分子内的。速率表明芳香族单元处于刚性区域,并且它们可能至少有两种不同的环境。未观察到与DNA有明显相互作用,这与色氨酸和酪氨酸单元不与碱基接触一致。
