Characterization Of The Poly (Adp-Ribose) Polymerase Family In The Fusarium Oxysporum Species Complex, Daniel Norment
Characterization Of The Poly (Adp-Ribose) Polymerase Family In The Fusarium Oxysporum Species Complex, Daniel Norment
Masters Theses
Fusarium oxysporum is a filamentous fungus that is known to invade over a hundred different hosts and poses a major threat to the economy and food supply world-wide. Poly (Adenosine diphosphate-Ribose) Polymerase (PARP) is a family of regulatory proteins that affect change in the cell through transfer of ADP-Ribose moieties onto target molecules. The most well-studied PARP protein is the human PARP1, a PARylating nuclear protein that serves as our model PARP protein. F. oxysporum was found to contain a large expansion of PARP catalytic-domain-containing proteins compared to other filamentous fungi. We utilized in silico multiple sequence alignments and domain …
Properties Of Potential Substrates Of A Cyanobacterial Small Heat Shock Protein, Yichen Zhang
Properties Of Potential Substrates Of A Cyanobacterial Small Heat Shock Protein, Yichen Zhang
Masters Theses
Most proteins must fold into native three-dimensional structures to be functional. But, newly synthesized proteins are at high risk of misfolding and aggregating in the cell. Stress, disease or mutations can also cause protein aggregation. A cyanobacterial small heat shock protein, Hsp16.6, can act as a chaperone to prevent irreversible protein aggregation during heat stress. This thesis is focused on the properties of proteins that were associated with Hsp16.6 during heat stress, and which therefore may be “substrates” of Hsp16.6. Bioinformatics were used to determine if Hsp16.6 preferentially binds to proteins with certain properties, and biochemical studies were performed to …
