Globins evolved from a common ancestor and can be divided into three lineages: Family M (for myoglobin-like) or F (for FHb-like), which has a typical 3/3 fold. Family S (for sensor-like), again with a 3/3 fold. Family T (for truncated), with a 2/2 fold All subfamilies can be chimeric, single-domain, or tandemly … See more The globins are a superfamily of heme-containing globular proteins, involved in binding and/or transporting oxygen.
