( 1998 ) Amphiphilic α-helices are important structural motifs in the alpha and beta peptides that constitute the bacteriocin lactococcin G – enhancement of helix formation upon alpha-beta interaction . Eur J Biochem 251 : 565 – 572 ....
True or False: A-form and B-form DNA are right-handed helices, but Z-form DNA is a left-handed helix found only in single-stranded DNA. Explain. Both RNA and DNA have a double helix structure. (a) True (b) False. True or false? In the W...
alpha-helical structure, which exhibits strong infrared dichroism, undergoes little H/D exchange, even after 48 h of D2O exposure. In contrast, non-alpha-helical structure, which exhibits little dichroism, undergoes rapid H/D exchange. A band at 1,640 cm-1, which has previously been assigned...
Deconvolution of the spectra, using a large reference dataset as specified in materials and methods, allowed to determine that 40% of KERP1 was folded in a-helices, 10% in ß-turns and 17% in turns while 29% was unordered (NMRSD of 0.01). If, more simply, a De (222 nm) of ...
Why are most alpha-helices right-handed? Why aren't humans ambidextrous? Why do stationary objects make good reference points? Why is there no refraction at a 90-degree angle? Why does Earth have a magnetic field? Why are there no rods in the fovea? Why do lenses have two focal points...
According to Govaerts et al., the left-handed β-rich helical structures containing α-helices are located outside of the β-helical struc- tures of prion fibers and are responsible for their toxicity (refer Figure 6(a)) [46]. In contrast, right- handed prion proteins are not toxic based...
The hydrophobic contacts between the center of the betaI domain and the alpha1/alpha7 helices are crucial for the low-affinity state of integrin alpha4 beta7. FEBS J. 2014;281(13):2915-26. doi: 10.1111/febs.12829. PubMed PMID: 24802248....

alpha-Helixmolecular tailoring approachDFTHydrogen-bond (H-bond) interaction energies in alpha-helices of short alanine peptides were systematically examined by precise density functional theory calculations, followed by a molecular tailoring approach. The contribution of each H-bond interaction in alpha-...
