PEGylation Promotes Hemoglobin Tetramer Dissociation

Web1 mag 2024 · In particular, haptoglobin (Hp) traps the αβ dimers of Hb, which are … WebWe conclude that the deoxy-Hb dimer, the unliganded dimer derived from liganded hemoglobin, and the HbCO dimer are identical in conformation, α 1 β 1; the first two are noncooperative in their ligand-binding properties. The hemoglobin tetramer is therefore the minimum unit capable of full cooperativity in ligand binding.
