Furthermore, they did not clearly distinguish permanent interfaces from transient interfaces.
In general, TIs are less evolutionarily conserved than permanent interfaces [ 50, 59- 61], but more conserved than the rest of the protein surface [ 48].
These results also implied that it is important to clearly distinguish permanent interfaces from transient interfaces when counting the number of a protein's distinct binding interfaces, because permanent and transient interfaces may contribute differently to protein evolutionary rate [ 37, 38].
On the other hand, co-expressed multi-interface hubs evolve at a significantly lower rate, indicating that hubs with more permanent interfaces are subject to higher evolutionary constraints and thus evolve more slowly.
For example, although a multi-interface hub is more likely to form a permanent complex with its partners through permanent interfaces, it does not rule out the possibility that the multi-interface hub forms a transient complex with its partners through transient interfaces.
However, TIs tend to be more difficult to predict than permanent interfaces [ 18, 20, 23, 27, 33, 39, 52, 55], possibly resulting from the weaker nature of the interaction manifesting itself as a weaker signal in the properties defining the interacting residues [ 27, 33, 52].
From the hardware point of view, traditionally, the personal computer accesses the flash memory through a permanent device interface, which implies a fixed point access of the memory.
One of the reasons for this situation is that after thermal treatment phosphorus species become condensed and occluded and have decreased solubility in water, whereas the other is the formation of a permanent phosphorus zeolite interface phase, as discussed in Section 3.1.
These are all-inorganic multicomponent nanoheterostructures in which domains of distinct materials are arranged via permanent bonding interfaces in elaborate concentric/eccentric onion-like or oligomer-type architectures.
Further, their inclination to allow Wall Street financial empires to dictate government economic policy has created a de-facto permanent government; an interface of the large Investment houses and the State complete with a well known cast of characters--like Robert Rubin and Henry Paulson--continually Paulson--continuallyrevolving door from one branch of the passingnthroughnmentheo the otherevolving
Particularly, we found significant differences in amino acid composition and residue residue preferences between interactions of residues within the same structural domain and between different domains, between permanent and transient interfaces, and between interactions associating homo-oligomers and hetero-oligomers.
