A Perspective on the (Rise and Fall of) Protein β-Turns

AG de Brevern - International Journal of Molecular Sciences, 2022 - mdpi.com
The β-turn is the third defined secondary structure after the α-helix and the β-sheet. The β-
turns were described more than 50 years ago and account for more than 20% of protein …

Stereospecific interactions of proline residues in protein structures and complexes

R Bhattacharyya, P Chakrabarti - Journal of molecular biology, 2003 - Elsevier
The constrained backbone torsion angle of a proline (Pro) residue has usually been invoked
to explain its three-dimensional context in proteins. Here we show that specific interactions …

Microtubule-associated AIR9 recognizes the cortical division site at preprophase and cell-plate insertion

H Buschmann, J Chan, L Sanchez-Pulido… - Current Biology, 2006 - cell.com
In plants, the preprophase band (PPB) of microtubules marks the cortical site where the
cross-wall will fuse with the parental wall during cytokinesis [1, 2]. This band disappears …

Local protein structures

B Offmann, M Tyagi, AG de Brevern - Current Bioinformatics, 2007 - ingentaconnect.com
Protein structures are classically described as composed of two regular states, the α-helices
