Structural features of transmembrane helices.
A total of 160 transmembrane helices of 15 non-homologous high-resolution X-ray protein structures have been analyzed in respect of their structural features. The dihedral angles and hydrogen bonds of the helical sections that span the hydrophobic interior of the lipid bilayer have been investigated. The Ramachandran plot of protein channels and solute transporters exhibit a significant shift D...
متن کاملFeatures of transmembrane helices useful for membrane protein prediction
For the development of a high-performance software system of membrane protein prediction, we analyzed the distribution of hydrophobicity and the amphiphilicity around transmembrane helices, using dataset of membrane proteins whose 3D structures or topologies are known. The moving average of 7 residues showed that there are a hydrophobicity peak in the center of a transmembrane helix and two amp...
متن کاملHow translocons select transmembrane helices.
Like all cellular proteins, membrane proteins are synthesized by ribosomes. But unlike their soluble counterparts, highly hydrophobic membrane proteins require auxiliary machineries to prevent aggregation in aqueous cellular compartments. The principal machine is the translocon, which works in concert with ribosomes to manage the orderly insertion of alpha-helical membrane proteins directly int...
متن کاملTMSEG: Novel prediction of transmembrane helices.
Transmembrane proteins (TMPs) are important drug targets because they are essential for signaling, regulation, and transport. Despite important breakthroughs, experimental structure determination remains challenging for TMPs. Various methods have bridged the gap by predicting transmembrane helices (TMHs), but room for improvement remains. Here, we present TMSEG, a novel method identifying TMPs ...
متن کاملA periodicity analysis of transmembrane helices
Transmembrane helices and the helical bundles which they form are the major building blocks of membrane proteins. Since helices are characterized by a given periodicity, it is possible to search for patterns of traits which typify one side of the helix and not the other (e.g. amphipathic helices contain a polar and apolar sides). Using Fourier transformation we have analyzed solved membrane pro...
