Folding of Aquaporin 1: Multiple evidence that helix 3 can shift out of the membrane core
The folding of most integral membrane proteins follows a two‐step process: initially, individual transmembrane helices are inserted into the membrane by the Sec translocon. Thereafter, these helicesExpand

A New Process for the Synthesis of Aurones by Using Mercury (II) Acetate in Pyridine and Cupric Bromide in Dimethyl Sulfoxide.
Syntheses of aurones 2a-i have been achieved by the oxidation of 2'-hydroxychalcones la-i with molar amount of mercury (II) acetate in pyridine and in catalytic amount of CuBr 2 in DMSO in goodExpand

Effect of active-site modification on the terminal marking deamidation of triosephosphate isomerase.
The conformational change which results from the opening and closing of the hinged lid over the catalytic center of triosephosphate isomerase is transmitted to the subunit interface of the dimer andExpand

Molecular features of steroid-binding antidins and their use for assaying serum progesterone
Chicken avidin (Avd) and streptavidin from Streptomyces avidinii are extensively used in bionanotechnology due to their extremely tight binding to biotin (Kd ~ 10−15 M for chicken Avd). We previouslyExpand
