Non-symbiotic hemoglobin 1

Function
May not function as an oxygen storage or transport protein, but might act as an oxygen sensor or play a role in electron transfer, possibly to a bound oxygen molecule. Has an unusually high affinity for O(2) because of a very low dissociation constant.
Similarity
Belongs to the plant globin family.
