An Insight Into The Biological Functions, The Molecular Mechanism And The Nature Of Interactions Of A Set Of Biologically Important Proteins., Adam A. Aboalroub

USF Tampa Graduate Theses and Dissertations

Characterization of protein structural properties is crucial to determine its role in normal and pathological conditions. In this dissertation, we have employed NMR spectroscopy in a combination of other biochemical and biophysical techniques to investigate the catalytic function, the molecular mechanism, and nature of the interactions of bmAANAT3, Cdc37, and TIMP2, respectively.

In the first project, we have employed an arylalkylamine N-acetyltransferases (AANATs) from Bombyx mori (bmAANAT3) to determine the role of the acetyl-group in coordinating the catalytic cycle in this family of enzymes. We have found that the occupancy of the acetyl-moiety in the catalytic funnel of these enzymes …

Identification And Characterization Of N-Acyltransferase Enzymes That Are Involved In The Biosynthesis Of Fatty Acid Amides, Daniel Robert Dempsey

USF Tampa Graduate Theses and Dissertations

Fatty acid amides are an emerging family of bioactive lipids that consists of N-acylethanolamines, N-acylarylalkylamides, N-acylglycines, N-acyl amino acids, N-monoacylpolyamides, and primary fatty acid amides. Short chain fatty acid amides are products of inactivated biogenic amines such as dopamine, histamine, octopamine, and serotonin, whereas long chain fatty acid amides have been implicated in a number of physiological process such as the perception and inhibition of chronic pain through binding to their specific receptors. The most famous; therefore, the most studied long chain fatty acid amide is anandamide or also known as N-arachidonylethanolamine. The biosynthesis …
