Researchers make discovery that will benefit pharmaceutical companies By David Crawford Staff Writer UTSA Researchers, led by Dr. Aimin Liu, professor and luther brown distinguished chair in biochemistry, made a discovery regarding fluorine, a reactive – and often toxic – chemical element found in water and air, also used in toothpaste and medicine. Not much is known about fluorine, aside from its toxicity. An example of this is seen in Parchment, Michigan, where water test results revealed the water to be tainted with perfluorooctanesulfonic, a man-made pollutant. As a result, the residents used and drank and used bottled water while the water supply was being decontaminated. Since fluorine is capable of forming strong bonds, the element can be beneficial to humans if it’s bonded with another element. This is the reason Liu used fluorine in his research. “We added fluorine to tyrosine [amino acid],” Liu said. “The purpose for that is fluorine is a very small atom and is chemically very electronegative, so it attracts electrons. This completely changes tyrosine’s reactivity.” Liu’s research team’s goal for bonding fluorine to tyrosine was to use fluorine’s strong bonding properties to slow the tyrosine enzyme’s autocatalytic process — it was a way to study how enzymes regulate the body’s thiol levels. “Once you eat, you get a lot of thiol and it needs to be controlled. Therefore, the enzyme starts to make itself much more efficient and each protein only mixes once. It’s technically very challenging to discover how this forms,” Dr. Liu said. Due to the protein’s single-use condition, and the fact that the enzymes form at irregular times, not much is known about the enzyme’s autocatalytic process. Thus, Liu hoped that having a carbon-fluorine bond (C-F bond) on the tyrosine amino acid would make it more difficult for the protein’s formation, so he could observe the process. Then, Liu discovered something about fluorine other than how enzymes regulate thiol. “During this process, the fluorine we added was lost. The C-F bond was cut. This is totally unexpected, because we were [taught] that the C-F bond is supposed to be one of the strongest, most durable bonds in organic chemistry,” Liu said. According to Liu, this discovery should draw the attention of pharmaceutical companies since more than 20 percent of drugs attach fluorine to modified enzymes, changing the reactivity and beContinued on page 2 See “Research team makes fluorine discovery”

Students living in Chaparral Village, Laurel Village and Alvarez Hall can only receive packages, but not United States Postal Service (USPS) mail at their individual addresses. “If they [students] wish to receive USPS letter mail they must rent a P.O. box at the UPS store,” Betty Meslow, an administrative associate in the office of housing and residence life (HRL) said. According to Meslow, these three dormitories receive packages only from UPS, FedEx, DHL and

Amazon. Drew Galloway, MOVE Texas executive director, thinks that UTSA students should also be able to receive USPS mail on all campus housing properties, in order to avoid difficulties as they try to vote in the next election. “MOVE Texas’ youth organizers register thousands of UTSA resident students every year,” Galloway said. “Voter registration cards are regularly returned to the Bexar County Elections Department due to insufficient dormitory addresses.” The registered student must then update their address at the polling location in order to vote in the next election. According to Kevin Price, senior associate vice president for student affairs

Office of Undergraduate Research moved to Univeristy College By Lauren Donecker Staff Writer Effective Sept. 1, the Office of Undergraduate Research has moved into University College as part of President Eighmy’s initiative focused on enhancing student success. According to Heather Shipley, vice provost for academic affairs and dean of university college, this move is a natural fit. “University College is devoted exclusively to

undergraduate students,” Shipley said. “Its focus is helping undergraduates to achieve academic success and to enrich their education by participating in experimental learning opportunities such as research.” President Eighmy announced his initiative on student success in Oct. 2017. The goal of this initiative was to improve the university’s retention and graduation rates dramatically by taking a studentcentric approach. In order to accomplish this goal, he

established a 25-member student success task force. This specific change aligns with Eighmy’s initiative on student success. “Undergraduate research – just like other experimental learning opportunities that take place outside of the classroom, such as internships or study abroad—can have a tremendously positive impact on a student’s success in college,” Shipley said. The expected results of these changes will broaden students’ opportunities and

make it easier for students to get involved in research. “Currently, more than 1,500 undergraduate students are involved in facultymentored research programs across the university,” Shipley said. “We want even more students to have those opportunities.” Some students perceive this change as a positive one. “President Eighmy’s Continued on page 2 See “Relocation of Office of Undergraduate Research”

Second annual Vigil for Unity By Javier Lopez Contributing Writer The second annual Vigil for Unity was held on the Paseo at The University of Texas at San Antonio on Sept. 13. The vigil was held against hate and violence and to promote unity within the African American community, while honoring those who died from this violence. The Black Law Student Association, Kappa Alpha Psi, and the black community of UTSA held the Vigil for Unity. Students gathered for this event even though San Antonio was experiencing rain.
