polyproline helix is a type of protein secondary structure which occurs in proteins comprising repeating proline residues. A left-handed polyproline II...

unfavorable backbone packing in the center of the helix. Other extended structures such as the polyproline helix and alpha sheet are rare in native state proteins...

helix is made of three collagen peptides, each of which forms its own left-handed polyproline helix. When the three chains combine, the triple helix adopts...

chain. Multiple prolines and/or hydroxyprolines in a row can create a polyproline helix, the predominant secondary structure in collagen. The hydroxylation...

FASCICULIN-II 1vzj: STRUCTURE OF THE TETRAMERIZATION DOMAIN OF ACETYLCHOLINESTERASE: FOUR-FOLD INTERACTION OF A WWW MOTIF WITH A LEFT-HANDED POLYPROLINE HELIX...

structure exon 1 and exon 3 corresponding peptides may take on is the polyproline helix (PPII), indicated by the high occurrence of proline and glycine in...

dimeric transmembrane β-helix. This peptide is secreted by gram-positive bacteria as an antibiotic. A transmembrane polyproline-II helix has not been reported...

the polypeptide has the conformation of beta sheet or of type II polyproline helix (PPII). A number of glutamines and asparagines help bind short peptides...

his co-worker Vladimir Kubyshkin, the new-to-nature hydrophobic polyproline-II helix foldamer was designed. Along with Budisa's previous work on bioexpression...

located from P185 to P188 has the secondary structure of a type II polyproline helix. This gene is found in primates but is also found at a very poor E-values...

PPI may refer to: PPi, the anion P2O74−, a pyrophosphate Polyproline I helix Protein–protein interaction Patient and public involvement Prepulse inhibition...

most common regions are labeled: α for α helix, Lα for left-handed helix, β for β-sheet, and ppII for polyproline II. Such a clustering is alternatively...

interesting secondary structure as a cluster of proline can form a polyproline helix. PRR12 contains a possible nuclear import signal starting at P1794...

C-α-branched side chains are known to adopt structure analogous to polyproline I helix. Different strategies have been employed to predict and characterize...

share the defining structural feature known as the triple helix, where three left handed polyproline II-type (PPII) helices assemble to form a right-handed...

domains. Binding of the enzyme to the thylakoid membrane involves a polyproline type II helix created between two FNR monomers and several proline rich integral...

acids are bound together to form a triple helix of elongated fibril known as a collagen helix. The collagen helix is mostly found in connective tissue such...
