The Identification of Critical Active-Site Groups and Catalytic Steps Governing the Desulfonation Reaction by Alkanesulfonate Monooxygenase 

Robbins, John (2012-10-08)
The alkanesulfonate monooxygenase enzyme (SsuD) catalyzes the oxygenolytic cleavage of a carbon-sulfur bond of sulfonated substrates. A mechanism involving acid-base catalysis is proposed for the desulfonation mechanism ...

Identification of Factors Contributing to Geographic Scale and Mode Choice of Long-Distance Travel 

Bacon, Benjamin (2014-07-11)
As long-distance travel increases it is emerging as an increasingly important consideration in transportation planning. Not only is this in response to an increase in magnitude but also in recognition that such trips possess ...

Identification of genes involved in the production of a novel antifungal agent (7, 10, 12-trihydroxy-8(E)-octadecenoic acid) in Pseudomonas aeruginosa 

Cofield, Jessica (2009-08-04)
The gram-negative bacterium Pseudomonas aeruginosa catalyzes the conversion of ricinoleic acid into a novel trihydroxy fatty acid, 7, 10, 12-trihydroxy-8(E)-octadecenoic acid (TOD), that has a potent antifungal activity ...

Identification of Geographic Origin of Ictalurid Catfish and Penaeid Shrimp by Elemental Profiling 

Li, Li (2012-07-18)
Three investigations were performed related to identification of geographic origin of aquatic products by elemental profiling and multivariate statistics. In the first study, fillets of channel catfish Ictalurus punctatus ...

Identification of heat tolerant upland cotton (Gossypium hirsutum L.) germplasm utilizing chlorophyll fluorescence measurement 

Wu, Tingting (2013-07-16)
Heat stress adversely affects upland cotton (Gossypium hirsutum L.) production in the U.S.. A low level of genetic variability in domesticated upland cotton is one of the major constraints for cotton germplasm improvement. ...

Identification of Individual Contributions to Total Flicker Levels in Electric Power Systems 

Gosnell, Ryan (2010-04-02)
Total flicker levels in an electric power system can be contributed to from multiple sources of flicker. Methodologies for allocating portions of this total flicker level to the responsible loads are studied. The representation ...

Identification of Molecular Biomarkers for Male Reproductive Success in Blue Catfish (Ictalurus furcatus) 

Hess, Hana (2022-04-27)
The overall objective of this project was to understand the underlying physiological and molecular processes that are associated with sperm production and function. The primary objective was to identify RNA biomarkers ...

Identification of new components involved in shoot gravitropism in Arabidopsis thaliana 

Sharma, Archana (2015-07-24)
Plants can reorient their growth according to environmental cues such as light, water, nutrients, gravity etc. Shoots (hypocotyls and inflorescence stems) of the plants exhibit negative gravitropism. Germinating seeds are ...

Identification of novel biosynthetic gene clusters and bacterial taxa from a soil microbiome using metagenomic approaches 

Pereira, Alinne (2021-04-21)
The microbial world is home to incredible taxonomic and metabolic diversity. Microorganisms are prolific producers of secondary metabolites, which are an important source of bioactive compounds, namely antibiotics, which ...
