The MIDI music
you will hear on this site has been created from the amino acid sequences of
different animal proteins. The
software used to generate the MIDI files is Bio2MIDI
Arts.) In Shark Music and
in Gecko Music the harmonizing line was produced using a composition
program to duplicate, transpose or offset the original melody.
Each piece is a
direct readout of the protein sequence, with specific pitches corresponding to
specific amino acids. The following animal proteins are represented on the
Sumatran Tiger Beta Globin:
Red Kangaroo Beta
Beta globin is part of
the structure of hemoglobin, the oxygen-tranport molecule of red blood cells.
The same beta globin sequence is also found in lions, jaguars and Persian
histocompatibility antigens are the ID cards for the cells of an organism. Each
individual has a unique set of these antigens. They function in the recognition
of foreign cells, and are important both in the immune response against
invading microorganisms and in graft rejection.
Hippo/Giraffe Alpha Lens
crystallins are proteins that make the lens of the eye clear and refractive.
Many lens proteins seem to have been recruited from enzymes and other proteins
originally serving other functions. This alpha crystallin is found in both
hippos and giraffes.
Rhino ATP Synthase A
When sugars are metabolized in the presence
of oxygen, mitochondria use the energy to synthesize ATP -- an important energy
intermediary in the cells of all organisms. ATP synthase, the enzyme that
makes the ATP, is a multiprotein complex embedded in the inner mitochondrial
membrane. ATP synthase A forms part of a channel protein through which
protons -- H+ ions -- flow and help to drive ATP synthesis.
Shark liver fatty-acid binding
This protein helps to
move fatty acids around within the cells of the shark's liver. Shark livers
contain high concentrations of fats. Since sharks don't have swim bladders to
keep them afloat, the fatty livers may increase their buoyancy.
Eastern Diamondback Venom
Many of the proteins
in snake venoms are modified digestive enzymes that attack either proteins or
lipids. One advantage of these enzymes is that besides helping to subdue the
snake's prey, the enzymes help to predigest the snake's food.
Gecko Blue-cone Receptor
Color vision in
vertebrates is a function of several receptor proteins in the cones of the
retina. There are separate proteins for blue, red and green light. These
proteins are similar in all vertebrates with color vision.
Myoglobin is a
muscle protein that stores oxygen. The molecule is similar to hemoglobin. The
muscles of active flyers, or in the case of the penguins, swimmers and divers,
are rich in myoglobin.
