Structure of DNA repair protein XRCC4 aka X-ray repair cross-complementing protein 4
XRCC4 protein is a TETRAMER that resembles the shape of a DUMBBELL containing two globular ends separated by a long, thin stalk. The tetramer is composed of two dimers, and each dimer is made up of two similar subunits. The first subunit (L) contains amino acid residues 1 â 203 and has a longer
Pterion and Pteron Notes
The pterion is the region where the frontal, parietal, temporal, and sphenoid bones join. It is located on the side of the skull, just behind the temple. Structure The pterion is located in the temporal fossa, approximately 2.6 cm behind an
Protein secondary structure
Protein secondary structure is the three dimensional form of local segments of proteins. The two most common secondary structural elements are alpha helices and beta sheets, though beta turns and omega loops occur as well. Secondary structure elements typically spontaneously form as a
Turn (biochemistry)
For beta turns, see Beta turn. A turn is an element of secondary structure in proteins where the polypeptide chain reverses its overall direction. Definition According to one definition, see Rose et al. 1985 in the References a turn is a structural motif where the CÎą a
β turns (also β-bends, tight turns, reverse turns, Venkatachalam turns) are the most common form of turnsâa type of non-regular secondary structure in proteins that cause a change in direction of the polypeptide chain
β turns (also β-bends, tight turns, reverse turns, Venkatachalam turns) are the most common form of turnsâa type of non-regular secondary structure in proteins that cause a change in direction of the polypeptide chain. They are very common motifs in&n
