In contrast, folding and assembly of these heterotetrameric protein complexes remain poorly understood. Similar to investigations of other multisubunit systems, in vitro Hb refolding experiments are often plagued by aggregation. This technique allows the observation of coexisting subunit combinations, heme binding states, and protein conformers. Hb reassembly is triggered by solvent exchange. Experiments conducted at room temperature provide a low metHb refolding yield. In the absence of aggregation-related interference, Hb assembly follows a symmetric pathway.

Heme-bound monomers then form heterodimers, and ultimately heterodimer association results in native Hb. This work highlights the utility of time-resolved ESI-MS investigations for interrogating the kinetic competition between on-pathway events and aberrant side reactions during the self-assembly of biomolecular complexes.
