New Reactions Of Strained Allyl Silacycles, Elizabeth Cummins May 2018

New Reactions Of Strained Allyl Silacycles, Elizabeth Cummins

Graduate Student Symposium

Ring-strained allylsilanes exhibit both electrophilic and nucleophilic characteristics, allowing for simultaneous activation and allylation of carbonyl compounds. Results are presented describing an optimized synthesis of certain allylsilacyclobutanes and their use in several selective carbon-carbon bond forming reactions.


Substrate Analogs For Characterizing The Substrate Tolerance Of S. Pneumoniae Srta, Orion Banks May 2017

Substrate Analogs For Characterizing The Substrate Tolerance Of S. Pneumoniae Srta, Orion Banks

Graduate Student Symposium

Bacterial sortases have been widely studied for their usefulness in protein modification, however, the variable substrate specificity and activity between homologs of these enzymes is not yet fully characterized. To attempt to further understand sorting signal recognition, we are working towards a substrate bound structure of sortase A from Streptococcus pneumoniae (SrtApneu). This enzyme displays a wide tolerance for alternate amino acids within the canonical LPXTG sorting motif. Our strategy involves a non-cleavable substrate analog that can be docked into the active site, allowing for elucidation of a structure displaying the key contacts that allow the enzyme to recognize ...
