Abstract:
We review computational methods to locate energy transport networks in proteins that are based on the calculation of local energy diffusion in nanoscale systems. As an illustrative example, we discuss energy transport networks computed for the homodimeric hemoglobin from Scapharca inaequivalvis, where channels for facile energy transport, which include the cluster of water molecules at the interface of the globules, have been found to lie along pathways that experiments reveal are important in allosteric processes. We also review recent work on master equation simulations to model energy transport dynamics, including efforts to relate rate constants in the master equation to protein structural dynamics. Results for apomyoglobin involving relations between fluctuations in the length of hydrogen bonds and the energy flux between them are presented.

Overview of Protein Sorting and Transport
Protein sorting can be of two types: signal-based sorting and vesicle-based trafficking. In signal-based sorting, specific amino acid sequences called sorting signals target proteins to the proper location inside the cell either via gated transport or by protein translocation. In gated transport, folded...
Translocation of Proteins into the Mitochondria
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
