A Two-Tailed Phosphopeptide Crystallizes to Form a Lamellar Structure

A Two‐Tailed Phosphopeptide Crystallizes to Form a Lamellar Structure

The crystal structure of a designed phospholipid-inspired amphiphilic phosphopeptide at 0.8 Å resolution is presented. The phosphorylated β-hairpin peptide crystallizes to form a lamellar structure that is stabilized by intra- and intermolecular hydrogen bonding, including an extended β-sheet structure, as well as aromatic interactions. This first reported crystal structure of a two-tailed pept...

a synchronic and diachronic approach to the change route of address terms in the two recent centuries of persian language

terms of address as an important linguistics items provide valuable information about the interlocutors, their relationship and their circumstances. this study was done to investigate the change route of persian address terms in the two recent centuries including three historical periods of qajar, pahlavi and after the islamic revolution. data were extracted from a corpus consisting 24 novels w...

A monoclonal antibody to the phosphorylated form of phenylalanine hydroxylase. Definition of the phosphopeptide epitope.

Monoclonal antibody PH7 has specificity for the phosphorylated form of the human liver phenylalanine hydroxylase and negligible reactivity towards the dephosphorylated form of the native enzyme by enzyme-linked immunoassay. PH7 binds specifically to the phosphorylated form of the liver enzyme after SDS/polyacrylamide-gel electrophoresis and transfer to nitrocellulose. Competitive blocking assay...

A Novel Structure for Realization of a Pseudo Two Path Band-Pass Filter

In this paper, a modified auto zeroed integrator is used to design and simulate a low-voltage high-Q switched capacitor pseudo 2-path filter.  The filter is a sixth–order Chebyshev band-pass filter operating at sampling frequency of 1MHz and center frequency of 250 kHz with a quality factor of 50. The proposed filter has both low-voltage and high speed properties of the auto zeroed integrators ...
