WebSep 24, 2015 · In vertebrates, myoglobin (Mb) and cytoglobin (Cygb) are closest relatives in the family of globins, which are heme-containing proteins that can bind gaseous molecules. Mb acts not only as an O 2 transporter but also a nitric oxide (NO) scavenger in cardiac and striated muscle. WebThe globin family includes eight different types of globins, but the best described and characterized in vertebrates are hemoglobin (Hb), myoglobin (Mb), cytoglobin (Cygb), and neuroglobin (Ngb). Hb is located in erythrocytes, which transport O 2 from the lungs to tissues through the circulatory system and CO 2 in the opposite direction.
