Data Scientific Study on Allosteric Regulation of Hemoglobin - The Role of Chloride Ion in Quaternary Structural Change-

In this letter, we investigated the contribution of bridging hydrogen bonds (BHB) via Cl- on the T-R transition of human adult hemoglobin (HbA). We applied the time-series clustering method to time-series data of the alpha beta dimer rotation angle phi and the total number of the BHBs. Compared with the above two results, we have concluded that Cl- BHBs do not significantly contribute to the structural regulation of HbA.

Automated summary

The investigation found that bridging hydrogen bonds via Cl- do not significantly contribute to the structural regulation of human adult hemoglobin.
