Pharmacological Chaperoning In Fabry Disease, Jerome Rogich
Pharmacological Chaperoning In Fabry Disease, Jerome Rogich
Masters Theses 1911 - February 2014
Fabry Disease is an X-‐linked lysosomal storage disorder characterized by a variety of symptoms including hypohydrosis, seizures, cardiac abnormalities, skin lesions, and chronic pain. These symptoms stem from a lack of functional endogenous α-‐ Galactosidase A (α-GAL), which leads to an accrual of its natural substrate. The severity of the disease symptoms can be directly correlated with the amount of residual enzyme activity. It has been shown that an imino sugar, 1-deoxygalactonojirimycin (DGJ), can increase enzymatic activity and clear excess substrate. This pH-‐dependent chaperoning phenomenon is believed to arise from the presence of aspartic acid 170 in the active site. …
Novel Adaptor-Dependent Domains Promote Processive Degradation By Clpxp, Keith L. Rood
Novel Adaptor-Dependent Domains Promote Processive Degradation By Clpxp, Keith L. Rood
Masters Theses 1911 - February 2014
Protein degradation by ATP dependent proteases is a universally conserved process. Recognition of substrates by such proteases commonly occurs via direct interaction or with the aid of a regulatory adaptor protein. An example of this regulation is found in Caulobacter crescentus, where key regulatory proteins are proteolysed in a cell-cycle dependent fashion. Substrates include essential transcription factors, structural proteins, and second messenger metabolism components. In this study, we explore sequence and structural requirements for regulated adaptor mediated degradation of PdeA, an important regulator of cyclic-di-GMP levels.
Robust degradation of PdeA is dependent on the response regulator CpdR in vivo …

Chemical Information Based Elastic Network Model: A Novel Way To Identification Of Vibration Frequencies In Proteins., Sharad K. Raj
Masters Theses 1911 - February 2014
A novel method of analysis of macromolecules has been worked upon through this research. In an effort to understand the dynamics of macromolecules and to further our knowledge, pertaining specifically to the low frequency domain and also to elucidate certain important biological functions associated with it, a theoretical technique of chemical information based Normal Mode Analysis has been developed. These simulations render users with the ability to generate animations of modeshapes as well as key insight on the associated vibration frequencies. Harmonic analysis using atomistic details is performed taking into account appropriate values of masses of constituent atoms of a …
