Synthetic utility of phenyl radicals generated in situ and a mechanistic study of the unusual reactivity of 2-oxazolines with aldehydes.
(2007)
There are few references to this unusual reaction in the literature and no mechanistic studies. Therefore, a mechanistic study has been carried in order to provide a better understanding of the reaction. These studies ...
Studies of molecular architecture within solid polymer electrolytes and teichoic acid biopolymers from solid-state nuclear magnetic resonance spectroscopy.
(2007)
The unsuccessful collection of a 31P CP-MAS spectrum in frozen D2O suggests the presence of liquid water around LTA. 2H SSNMR were used to study the phase of the water environments for LTA dissolved in D2O at -25 and ...
Design and synthesis of bistable and tristable [2]catenanes as probes for non-covalent molecular interactions.
(2007)
With wider bis(p-benzyl)methyl spacers in 4,4'-dipyridinium macrocycles interlocked with the BPP34C10, four symmetric [2]catenanes have been studied. Symmetric blocking groups on tethers enabled either pathway for ...
The Effect of Strong Electric Fields on Tyrosine Hydroxylase Activity
(2009)
Tyrosine hydroxylase (TH) catalyzes the first and, more importantly, the rate-limiting step in the biosynthetic pathway of the catecholamine neurotransmitters dopamine, norepinephrine and epinephrine. The regulation of ...
KINETIC STUDIES OF SACCHAROPINE REDUCTASE
(2009)
Saccharopine reductase (SR) (EC 1.5.1.10) is the penultimate enzyme in the L-αaminoadipate pathway encoded by the LYS9 gene in Saccharomyces cerevisiae. Saccharopine reductase (SR) catalyzes the condensation of ...
The structure and function of YPD1, a histidine-containing phosphotransfer protein from yeast.
(2001)
Finally, through molecular modeling and structural comparisons, a general model of how YPD1 and response regulator domains might interact was proposed. It seems likely that YPD1 binds to response regulator domains through ...
Conversion of aromatic amines and N-aromatic amides to O-aromatic esters, biphenyls, aromatic halides and energetic materials via nitrosamide intermediates.
(2002)
These reactions can be carried out directly on aromatic amines (initial in situ acetanilide formation) to give aromatic acetates, and halides in good to excellent isolated yields. The mechanism, scope, potential utility ...
Identification and analysis of the response regulator binding site on the surface of the histidine-containing phosphotransfer protein YPD1 from Saccharomyces cerevisiae.
(2003)
The results from the yeast two-hybrid screens were confirmed by the X-ray crystal structure of the SLN1-R1/YPD1 complex. This structure is the first to reveal protein-protein interactions between a monomeric HPt domain and ...
Mechanisms of electrophilic aromatic substitution reactions of (eta('6)-arene)molybdenum(phosphine)(, 3) complexes.
(2000)
The mechanism of protonation of (eta6-C6H 6)Mo(TRIPOD) (1) (TRIPOD = tris(1,1,1-diphenylphosphinoethyl)methyl ethane) to give [(eta6-C6H6)MoH(TRIPOD)] + was reported to involve a cyclohexadienyl intermediate. In this ...
Spectroscopic Study of Amine Salts and Polyamine Salt Systems
(2009)
Fundamental research is a necessary foundation for advanced technological development and application. Progress in improving application-based systems largely depends on understanding the nature of the system. A better ...
