Polypeptides traverse the mitochondrial envelope in an extended state

Functional histone antibody fragments traverse the nuclear envelope

Factors important in the translocation process of proteins across the nuclear membrane were studied by microinjecting either fluoresceinated nonimmune IgG and F(ab)2 or the corresponding molecules, prepared from antisera to histones, into the nucleus and cytoplasm of human fibroblasts. Intact IgG from both preparations remained at the site of injection regardless of whether it was injected into...

An Analytical Equation of State Extended to Copolymers

calculate some thermodynamic properties of molten polymers including specific volume and isothermal compressibility (S.M. Hoseini, Physical Chemistry & Electrochemistry, 2 (2014) 56-65). This work extended that EOS to predict the volumetric properties of some molten ethylene copolymers including ethylene/1-octene, ethylene/1-butene (xethylene equal to 0.8543 and 0.563), ethylene/propene. The ab...

Effect of temperature on the circular dichroism spectra of polypeptides in the extended state.

Respiratory syncytial virus polypeptides. III. The envelope-associated proteins.

Four proteins, GP1, VGP48, GP26 and VPM27, are associated with the envelope of respiratory syncytial (RS) virus. The status of GP1 has been uncertain, because a cellular glycoprotein migrates at the same position when Laemmli's discontinuous buffer system is used for PAGE, and because BSC-1 cells infected with the RSN-2 strain of RS virus appear not to contain GP1. However, additional evidence ...

Sgr – Super - Eddington source enshrouded by an extended envelope

An optical spectroscopy of an unusual fast transient V4641 Sgr constrains its mass to 8.7-11.7M (9.6M is the best fit value) and the distance to 7.4–12.3 kpc (Orosz et al. 2001). At this distance the peak flux of 12 Crab in the 2–12 keV energy band, measured by ASM/RXTE, implies the X-ray luminosity exceeding 2−3 ·1039 erg/s, i.e. near or above the Eddington limit for a 9.6M black hole. An opti...
