Functional conversion of myoglobin bound to synthetic bilayer membranes: from dioxygen storage protein to redox enzyme | Journal of the American Chemical Society (acs.org)
echniques to produce functional, artificial nanostructures have been developed.(9, 17, 21-27) The structures that can be created artificially follow one of two major methodologies: (i) using nature as a guide in the creation of biomimetic systems;(1, 8, 10, 14, 15, 17, 18, 20, 28-30) or (ii) creating entirely synthetic and distinctively unnatural assemblies.(1, 8) While both methods enjoy the benefits of the “bottom-up” approach,(1, 3-5, 18, 31) only the biomimetic route benefits from enhancements made during millennia of natural selection, while still retaining the flexibility to take advantage of new ideas.(7, 10, 17, 32, 33)The self-assembly of amphiphilic molecules in aqueous environments is an

at the core, it is an oxygen-binding protein in red blood cells. In humans, myoglobin is only found in the bloodstream after muscle injury. High concentrations of myoglobin in muscle cells allow organisms to hold their breath for a longer period of time. Diving mammals such as whales and seals have muscles with particularly high abundance of myoglobin. Myoglobin is found in Type I muscle, Type II A, and Type II B, but most texts consider myoglobin not to be found in smooth muscle. Myoglobin was the first protein to have its three-dimensional structure revealed by X-ray crystallography. This

Most organisms require molecular oxygen in order to survive. The dioxygen is
used in a host of biochemical transformations, although most is consumed in
the reaction

that is the terminal (or primary) step of oxidative phosphorylation (Chapters 5
and 6). For some small animals and for plants, where the surface-to-volume
cr400085m 1..75 (acs.org)ratio is large, an adequate supply of dioxygen can be obtained from simple
diffusion across cell membranes. The dioxygen may be extracted from air or
water; for plants that produce dioxygen in photosynthesis, it is als
