Structure-function studies of SLC15 peptide transporters
… and di- and tri- peptides and drugs similar in structure (peptidomimetics). PepT1, and to a lesser extent PepT2, have therefore gained attention due to their role in determining the absorption, retention and elimination of transported drugs. In this study three novel prodrug-carriers namely …

Structure-Function Studies on Two Phosphoenolpyruvate Carboxylases
… and C₄ plants via Rubisco. We are studying the structure-function aspects of both enzymes, with a goal of discovering new elements in these enzymes which can modulate catalysis. We have undertaken an interdisciplinary approach for this work and have shown that a combination of experimental and …

STRUCTURE-FUNCTION STUDIES OF NOVEL MEDICALLY RELEVANT FLAVOENZYMES
… has been shown to be essential for MICAL function, but its catalytic activity has not been defined yet. At variance with PHBH, MICAL-MO exhibits a detectable NADPH oxidase activity. The rate of the overall reaction is fully determined by that of enzyme reduction by NADPH, which takes place …

Structure-Function Studies of a Truncated Ice-Nucleation Protein
… subzero temperatures. Despite having an opposite function to antifreeze proteins (AFPs), INPs and AFPs both have significant similarities in sequence and structure. Based on these common features, I hypothesize that INPs also organize water molecules on their surface into ice-like geometries, as …

Structure-function studies of human SLC36 amino acid transporters
… (hPATs).This is due to hPATs 1 and 2 having been functionally characterized as proton coupled transporters that bring about a 1:1 symport of H+ and an amino acid across the membrane (with optimum uptake at an extracellular pH of 5.5). Their main substrates were found to be the small neutral amino …

Structure-function studies of the Parkinsonism-linked protein DJ-1
DJ-1 is a multifunctional protein linked to familial Parkinson’s disease. DJ-1 has been suggested to exert its cytoprotective function, in part, by acting as a copper carrier that can sequester the reactive metal and/or provide the copper cofactor for the activation of the Cu-Zn superoxide …

STRUCTURE-FUNCTION STUDIES OF TRANSLOCATED EFFECTORS FROM THE LATE BLIGHT PATHOGEN
… basis of disease. Determining the adaptive functions of effectors might reveal previously unexploited management strategies. This work details structure-function studies of two translocated effectors from the late blight pathogen; PexRD2, a representative RXLR effector, and CRN8, an effector …

Structure/Function Studies on Vps9 domain-containing Ankyrin Repeat protein (VARP)
… interaction with Vps29. The Varp:Vps29 complex structure was determined by a combined X-Ray Crystallographic/NMR method. This thesis demonstrates that one zinc knuckle sequence of Varp is sufficient to form an interaction with Vps29, with an affinity in the micromolar range. Single point …

STRUCTURE-FUNCTION STUDIES OF MULTIPLE INOSITOL POLYPHOSPHATE PHOSPHATASES FROM GUT COMMENSAL BACTERIA
… In this study, high resolution X-ray crystal structures of Minpps from two human commensal gut bacteria, Bacteroides thetaiotaomicron (BtMinpp) and Bifidobacterium longum (BlMinpp), were solved and refined. High performance liquid chromatography was employed to analyse the products of InsP6 …

Discovery of a Novel Metalloregular Family: Structure/Function Studies of E. Coli Rcnr
… and protein translation. Despite these essential functions, excess metal ions can lead to cell death through the generation of oxidative damage or the occupation of non-native metal sites. Acquiring metal ions from the environment while limiting possible toxic effects requires the coordinated …

Modification of bovine beta-casein using genetic engineering and its structure/function studies
Item marked as restricted to the 'UIUC Users [automated]' Group (id=2) by Howard Ding (hding2@illinois.edu) on 2011-05-07T14:55:53Z Item is restricted indefinitely.

Structure-function studies of respiratory complex I from Paracoccus denitrificans using membrane mimetics
… system for studying its mechanism. However, the structure of the enzyme remains unknown, due to its intrinsically flexible and fragile nature, restricting the power of the system to tackle specific mechanistic questions on the molecular level. This study employs a multifaceted approach to develop …

Structure-Function Studies on Human Epithelial Cystic Fibrosis Chloride Channels Expressed in Xenopus Laevis Oocytes
… split channels 1-633 plus 837-1480 were functionally similar to 1-835 plus 837-1480, including enhanced apparent ATP affinity and less tight binding of AMPPNP, but were more active before phosphorylation. Intriguingly, 1-633 plus 837-1480 channels, lacking the R domain, were still …

Structure-Function Studies of CorA-Mrs2-Alr1 Superfamily of Magnesium Channels: Bacterial CorA and Yeast Alr1
… This thesis details the investigation of the structure-function relationship of the bacterial CorA and yeast Alr1 using biophysical, biochemical and bioinformatic approaches. Members of the CorA-Mrs2-Alr1 superfamily contain a canonical GMN motif located at the entrance to the ion …

PLP-Dependent α-Oxoamine Synthases: Phylogenetic Analysis, Structural Plasticity, and Structure-Function Studies on 5-Aminolevulinate Synthase
… plasticity of ALAS has been documented in studies of functional circularly permuted ALAS variants and the single polypeptide chain ALAS dimer (ALAS/ALAS) exhibiting a greater turnover number than wild-type ALAS. An examination of the contribution of each ALAS/ALAS active site to the …
