Conformational relaxation and kinetic hole-burning in sperm whale myoglobin
… 80K is a result of kinetic hole-burning. In sperm whale Mb the band width decreases by about 2% and the peak shift is about 7.5% of the total width after 50% of all ligands have rebound. The data are consistent with a small inhomogeneous broadening. The underlying homogeneous width is …

Genetic analysis of the sperm whale (Physeter macrocephalus) using microsatellites.
The sperm whale is the largest of the toothed whales (Odontoceti), and inhabits deep waters from equatorial to Polar Regions. Sperm whales are social and commonly l r . found in small groups. However, sociality varies according to sex and age. Immature males form bachelor groups that disperse as …

A First Step Towards Understanding Sperm Whale Communication and Behavior
… patterns. In this work each section uses sperm whales as the species of focus, however the work is easily adaptable and applicable to any species that we can collect audio or movement data for.

The kinetics of protein conformational relaxation in sperm whale myoglobin following a pressure jump
… MPa) dependence of the CO stretching bands in Sperm Whale Myoglobin, Mb, in various solvents has been studied with FTIR spectroscopy. The data are consistent with hierarchically ordered conformational substates, csn' (nth tier), for the protein-ligand-solvent system. The spectra can be resolved …

Decoding the Depths: Developing a Click Separator for Predictive Speaker Recognition in Sperm Whale Conversations Using Machine Learning
… the development of a tool that transcribes sperm whale communication similar to how human speech is recorded and transformed into written text. Sperm whales communicate using a sophisticated system of clicks and codas. Listening through hundreds of hours of sperm whale audio recordings, …

Solution structure and dynamics of myoglobin and its mutants
… discusses the solution structure and function of sperm whale myoglobin. The solution structure of sperm whale myoglobin, with atomic resolution is obtained by using nuclear magnetic resonance spectroscopy (NMR).

Partial structural characterization of the cytoplasmic hemoglobin of Nostoc commune UTEX 584 expressed in Escherichia coli
… quite unlike those of leghemoglobin a and sperm whale myoglobin, which are used as references of comparison. For example, the optical spectral properties of oxycyanoglobin are different from those of leghemoglobin α and sperm whale myoglobin. In addition, the met-form of cyanoglobin has …

Scrimshaw: unlocking the cultural and biological archive of sea mammal art
… ‘scrimshaw’, predominantly using the teeth of sperm whales (Physeter macrocephalus), flourished among the crews of industrial whaling ships. Scrimshaw collections represent a unique cultural and biological archive of pre-industrial/industrial sperm whale populations, but the rarity, …

The Influence of Pressure on The Low-Temperature Kinetics of Myoglobin
… of carbon monoxide and dioxygen to horse and sperm whale myoglobin at low temperatures (60 - 160K) was studied using high pressure flash photolysis techniques. By comparing the pressure dependence when the system is first frozen and then pressurized with the pressure dependence when the system …

Replacement of Val3 In Human Thymidylate Synthase Affects Its Kinetic Properties and Intracellular Stability, Complexes of Sperm Whale Myoglobin G65T With Phenol and Ethylene Glycol, and Structure of A Fragment of Human End-Binding Protein 1 (Eb1)
… inhibitory site.</p> <p>CHAPTER 2: COMPLEXES OF SPERM WHALE MYOGLOBIN (MB) G65T WITH PHENOL AND ETHYLENE GLYCOL.</p> <p>Sperm whale myoglobin (Mb) mutants at position 65 were designed to mimic the heme environment of homologous dehaloperoxidase (DHP). The distance between the distal histidine and …

Structural heterogeneity and conformational relaxation in heme proteins
… rate upon the structural heterogeneity of sperm whale myoglobin solutions at cryogenic temperatures was studied. Sample cooling rates were varied by almost four orders of magnitude. FTIR spectra of the CO stretch frequency region reveal that the population of the A states is highly …

Infrared-monitored flash-photolysis of carboxymyoglobin
… A$\sb0$, A$\sb1$, and A$\sb3$ conformations of sperm-whale myoglobin (Mb) at atmospheric pressure and neutral pH are reported. The A$\sb0$, A$\sb1$, and A$\sb3$ rebinding kinetics are shown to be non-exponential and parameterized by activation-enthalpy distributions differing in prefactor …

Design and Synthesis of Redox or Catalytically Active Artificial Metalloproteins Containing Non-Native Inorganic and Organometallic Complexes
… sites of cytochrome c peroxidase (CcP) and sperm whale myoglobin (Mb) using cysteine residues. The new metalloproteins were characterized by UV-Vis, CD, electrospray mass spectroscopy and cyclic voltammetry. Together with chemical reactivity studies, these results demonstrated that the …

Near infrared transient absorption spectra of photolyzed myoglobin at low temperatures
… the transient absorption spectrum of photolyzed sperm whale carboxymyoglobin as a function of temperature and time after photolysis. Our measurements extend from 60K to 220K and from three microseconds to thirty seconds. We see an absorption band near 758 nm which is known as band VIII. Three …

Control of Ligand Binding to Heme Proteins: The Role of The Distal Histidine
… on the recombination rates of CO and O(,2) to sperm whale myoglobin, separated beta chains of normal human hemoglobin and to the beta chains of hemoglobin Zurich. The recombination was measured using flash photolysis from 300 to 40 K, on a time scale of 100 ns to 300 s. Lowering the pH of the …

Isolation and Genomic Analysis of the Cetacean Y-chromosome
… or microdissection is reported for the killer whale (Orcinus orca). Microdissected Y-chromosomes from the killer whale and bottlenose dolphin (Tursiops truncatus) were screened for sequences containing microsatellite motifs. 15 and 10 male-specific microsatellites were identified from the …
