BIOCHEMISTRY OF HEMIN UPTAKE IN LISTERIA MONOCYTOGENES AND THE FUCTION OF TONB IN ESCHERICHIA COLI
(2009)
Iron is an essential metal element for the metabolism pathway of most microorganisms. For pathogens, iron is also an important factor for virulence. But in the host body, the availability of free iron is very low. Iron ...
POLY(ETHYLENIMINE)-BASED ELECTROLYTES FOR BATTERIES AND FUEL CELLS: SYNTHESIS, MODIFICATION AND CHARACTERIZATION
(2009)
Poly(ethylenimine) (PEI) is an ion conducting polymer with great potential for applications in lithium batteries and proton exchange membrane fuel cells. Branched poly(ethylenimine) was N—methylated via an ...
Characterization of Poly(propylenimine) and Poly(N-methylpropylenimine) as Polymer Electrolytes with N,N'-dimethylethylenediamine and N,N'-dimethylpropylenimine as Model Compounds
(2009)
Many factors including light weight, flexible form factor, processing ease and environmental friendliness make solid polymer electrolytes (SPEs) desirable materials for use in lithium ion battery systems. However, consistently ...
The medicago truncatula genome and analysis of nodule-specific genes
(2009)
The nitrogen-fixing plant Medicago truncatula is an important model system for identifying legume genes and determining their functions. With over 255 megabases of the genome, representing about 85% of the euchromatic ...
Mechanisms of Serine Acetyltransferase and O-Acetylserine Sulfhydrylase
(2009)
The de novo biosynthesis of L-cysteine in enteric bacteria and higher plants is a two-step pathway. The first step is catalyzed by serine acetyltransferase (SAT), which converts acetyl CoA and L-serine to O-acetyl-L-serine ...
MECHANISTIC INVESTIGATION OF ADDITIONS TO ALKENES
(2009)
We have conducted correlation studies on ten alkene addition reactions in this project in order to explore the substituent effects on alkene reactivity in these reactions. In these studies, we have correlated the relative ...
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 ...
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 ...
SEQUENCE AND ANALYSIS OF THE
(2009)
Phymatotrichopsis omnivora, a soilborne fungus confined to the southwestern regions of the United States, causes root rot in more than 2,000 species of dicotyledonous plants. To investigate the gene repertoire in this plant ...
