One α-subunit and one β-subunit will come together to form a heterodimer, and two of these heterodimers will interact to form one hemoglobin molecule. Hemoglobin can therefore be thought of as a dimer of dimers, which come together to give the final protein its quaternary structure. View ...

A process whereby an active site in a protein (enzyme) is regulated by the binding of a molecule to a different site (typically distal in space). Knockouts Genes that have been inactivated (for example, deleted). Rights and permissions Reprints and permissions About this article Cite this arti...
Therefore, interactions forming on the outer surface of a protein molecule are preferred. The knowledge of the evolutionary mechanisms for protein thermostabilization, some of which are revealed by this study, can help us to engineer proteins with enhanced thermostability for practical purposes. ...
Included in the dataset were 24 homodimeric complexes whose asymmetric unit contained only half the structure. The full coordinate files were obtained from the NDB, which calculates the coordinates for the complete molecule by applying the transformation matrices provided in the PDB files to the half...
While a protein molecule is in fact only partially flexible about its peptide bonds, if we can show thata completely flexible model cannot be deformed into a plane, then the protein, with less flexibility than themodel, also cannot attain a planar conformation. Thus, for the purpose of ...
The model and cryo-EM density of the bound spermine (at a map threshold of 1.13), a water molecule (in red sphere), the upper phospholipid (using the unsharpened map at a map threshold of 0.51) are shown. c, Electrostatic surface distribution of the modelled surface of CaSR in the ...

Its overall structure is similar to that of neural-cell adhesion molecule (N-CAM). MAG in rodents occurs in two developmentally regulated isoforms, which differ in their cytoplasmic domains and are generated by alternative splicing of its mRNA. The isoform with a longer C-terminal tail (L-MAG...
