The accuracy and consistency of the new Nessler tube method were systematically studied versus the traditional acid-base titration and average chainlength methods through concentration measurements on polyphosphoric acid with concentrations ranging from 110% to 119%.

Therefore, we characterized the Cyt c P71H/M80V variant protein electrochemically and spectroscopically. All the experimental results showed that the introduced histidine at position 71 did not act as a functional distal-histidine, but most likely coordinated to the heme iron, maybe due to the flexibility of theΩloop segment (resides 70-84) of Cyt c protein.

于是我们对P71H／M80V蛋白性质进行了一系列的研究，结果表明可能是由于Cyt c中Ωloop D肽段(residues 70-84)具有很强的柔韧性，使得His71并没有象HRP中的distal histidine一样起到酸碱催化功能，而是与heme发生了配位作用，无论是在氧化态还是还原态都成了heme的第六轴向配体。
