Apocytochrome b₅ with a typical heme-binding motif of HPGG, and its variants with mutated motifs, GPGG, GPGH, HVGG,and HPGP, have been subjected to molecular dynamics simulation. Comparison of the dynamic consequences has revealed the crucial role of HPGG in assembling the heme group of cytochrome b₅ and in modulating protein structure, property and function.
