Ligand Migration in Sperm Whale Myoglobin
Biochemistry, 1997Geminate oxygen rebinding to myoglobin was followed from a few nanoseconds to a few microseconds after photolysis for more than 25 different oxymyoglobin point mutants in the presence and absence of 12 atm of xenon. In all cases, two relaxations were observed: an initial fast phase (half-time 20 ns) and a slower, smaller phase (half-time 0.5-2 micros).

Sperm whale clicks: Directionality and source level revisited
The Journal of the Acoustical Society of America, 2000In sperm whales (Physeter catodon L. 1758) the nose is vastly hypertrophied, accounting for about one-third of the length or weight of an adult male. Norris and Harvey [in Animal Orientation and Navigation, NASA SP-262 (1972), pp. 397–417] ascribed a sound-generating function to this organ complex.

The monopulsed nature of sperm whale clicks
The Journal of the Acoustical Society of America, 2003Traditionally, sperm whale clicks have been described as multipulsed, long duration, nondirectional signals of moderate intensity and with a spectrum peaking below 10 kHz. Such properties are counterindicative of a sonar function, and quite different from the properties of dolphin sonar clicks.

Function of the Spermaceti Organ of the Sperm Whale
Nature, 1970THE structure of the head of the sperm whale (Physeter catodon) was described in outline by Pouchet and Beauregard1–3 and by Raven and Gregory4, but the function of the large, wax filled spermaceti organ and related structures is not known although several theories4–6 have been advanced.

Properties of Components of Myoglobin of the Sperm Whale
Nature, 1964RUMEN1 isolated from seal, by chromatography on CM-cellulose in tris buffer at pH 8.5, five myoglobins all with the same iron content and the same N-terminal, but showed differences in isoelectric points. Akeson and Theorell2 isolated, from horse muscle, three myoglobins with similar amino-acid compositions but had charge differences.

Binding of Cyclopropane to Sperm Whale Myoglobin
Nature, 1967THIS article follows reports of the binding of xenon, an anaesthetic agent, to sperm whale met and deoxymyoglobin1,2. X-ray diffraction analysis showed that a single xenon atom binds to the same specific site in both derivatives. This site is located at a cavity in the interior of the molecule, about equidistant from the haem linked histidine and one ...
