Interaction Between Maltose Binding Protein And Escherichia Coli Maltose Transporter, Yan Huang
Interaction Between Maltose Binding Protein And Escherichia Coli Maltose Transporter, Yan Huang
Open Access Theses
The ATP-binding cassette (ABC) transporter superfamily is one of the largest families of transport proteins. The ABC transporters are responsible for selective permeability of solute across membranes energized by ATP hydrolysis, which occurs in all domains of life. Maltose transporter is an ABC importer that mediates maltose/maltodextrin uptake in bacteria and archaea. It is identified as an essential virulence factor in pathogenic species of Streptococcis pyogenes and Vibrio cholera (1, 2). Escherichia coli maltose transporter is a well-characterized system with crystal structures and exclusive biochemical studies available. Knowledge of the E. coli maltose transport mechanism will lead to a better …

Development Of A Starch-Based Mussel-Mimetic Adhesive Polymer, Jeffrey Kazimir De Kozlowski
Open Access Theses
Mussel-mimetic adhesive polymers have gained lots of attention for their strong adhesive strength, moisture resistance, and unique ability to crosslink. These properties are mainly attributed to the high content of catecholic 3,4-dihydroxyphenylalanine (DOPA) in mussel adhesive proteins. While there has been success in creating mussel-mimetic synthetic polymers, less effort has been given to create a renewable, green, biocompatible counterpart. This thesis explores the possibilities of starch-based mussel-mimetic adhesives. Carboxymethyl starch of various molecular weights and degree of substitution was synthesized and subsequent conjugation of dopamine to these polymers by 1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide was investigated. The polymers suffered from very low substitution (DScatechol …
