Myoglobin. Gene. MB. Organism. Physeter macrocephalus (Sperm whale) (Physeter catodon) Status. Reviewed-Annotation score: Experimental evidence at protein level i. Function i. Serves as a reserve supply of oxygen and facilitates the movement of oxygen within muscles. Annotation score: 3 out of 5. If you look at John Kendrew's PDB file, you'll notice that the myoglobin he used was taken from sperm whale muscles. Whales and dolphin have a great need for myoglobin, so that they can store extra oxygen for use in their deep undersea dives. Typically, they .
In order to investigate the influence of protonation on the structure of myoglobin, we determined the crystal structures of sperm whale myoglobin to 2.0 A or better in different states of ligation (MbCO, deoxyMb and metMb) at pH values of 4, 5 and 6.Cited by: 357. The sperm whale's unique body is unlikely to be confused with any other species. The sperm whale's distinctive shape comes from its very large, block-shaped head, which can be one-quarter to one-third of the animal's length. The S-shaped blowhole is located very close to Class: Mammalia.
Jul 05, 2013 · The protein myoglobin provides new clues to the evolution of diving in mammals. The Evolution Of Diving In Mammals And Myoglobin. By Paul . Abstract. Sperm whale myoglobin was expressed in Escherichia coli from a totally synthetic gene inserted in the expression vector pUC19. The gene was constructed as 23 overlapping oligonucleotides encoding both strands of the DNA.Cited by: 326.
